I agree with Shotglass, don't do it if you are not sure about what to do. You could lose data, your trying can result in a corrupted OS, not to mention hardware damages. and I didn't talked about LFS's sensitivity for instable (OC'ed to the limit) system. Your CPU seems to be enough for LFS, if you have the budget, try to get a better vga card (for example Ati 9550, Nvidia 6200).
hát persze hogy van megoldás. 
A kártya hibás, vidd vissza az üzletbe, ahol vetted. más játékokban is produkálja a hibát?
in english: I guess David's vga card is faulty, I recommended him to take it back to the shop where he bough it, and ask for a replacement.

,,The autoX course is so bad I can't see anything if I'm pointed in a certain direction."
Those tracks with lots of objects stresses (heats up) most
the graphical processor unit's vertex (geometric) pipelines.
,,...The artifacts go away if I turn off the hardware vertex shader..."
Offloading the videocard's geometric pipelines reduces the temperature.
...,,the game runs for 20 seconds, freezes for a minute, runs for 20 seconds, etc..."
It's called ,,thermal throttling." The vga card stops responding and underclocks itself to prevent damage caused by overheating.
-Is the cooler OK?
-Are you overclocking the card? If yes, disable OC.
-Try to reduce the GPU's core clock for testing.
-Is there any PCI card in the closest slot next to the VGA card? If yes, place it to another slot.
-Dualview gaming used to cause problems for old cards (ATI 9800 Pro, NV FX5900) in stressful 3D games. I remember a HardOCP review, where those graphics processors were tested with Flight Simulator 2004.
The 9800 Pro started to produce graphics anomalies, the FX5900 simply fried. Try gaming in single display mode.

The problem is that the Intel GMA 950 has no ,,hardware transform& lighting" and ,,hardware vertex shading" capabilities and since (as Scawen said) LFS's graphics are all about vertexes, you would get low fps at full grid or at heavy racing traffic.
Check out this review about the GMA 950's gaming performance:
http://www.anandtech.com/video/showdoc.aspx?i=2427
As you can see, the ATI Xpress 200M (thanks to its hardware T&L capabilities) performs much better than Intel's solution.
I had an Acer Laptop with a Celeron M CPU (OC'ed to 2 GHz for testing) with X200M graphics card. At 1024x768 screen resoltion in wheels view(medium graphics settings were applied) the system produced 18 FPS with a full grid of FZRs taking (and some of the racers crashing) 1st turn at an Aston North GP replay. The performance normalized at across 50 FPS when the drivers pulled away from each other.
Than I bought an Asus laptop which has an AMD Mobile Sempron 3400+ CPU and nVidia Go6100 VGA (with hardware vertex shading capabilities).
As I enabled hardware vertex shading option, the CPU offloaded from counting graphics, this way the new system produced 24 FPS at 1280x800 with the same Aston replay. Naturally this machine performs much better too when I see more cars front of me.
OK, so what to do?
1. Testing! Ask someone who has an Apple product with the same specifications to the one you desire to buy, for running LFS on it with a full grid of AI. Maybe the Core2Duo's performance is enough to produce acceptable performance (at least 24 fps) with the GMA 950.
2. How about collecting some more money, and buy your model with ATI x1600?
Sadly, dedicated VGA's are eating too much power compared to the integrated solutions, so prepare for qucikly depleting battery.
3. Most notebooks and laptops are not really designed for gaming (ok, so why I play on it? The answer is simple: I care only about LFS and I don't need gaming desktop PC which eats more power in idle, than my notebook at full throttle).
Using 3D applications requires powerful hardware. But more power= more heat (and more weight because of advanced cooling system) and the last but most important: poor battery performance. The result: a not really portable equipment.
4. Get the product, bulid a desktop PC for ,,backup" and playing games. Remember, a notebook is hardly (and expensively) upgradeable, unlike a desktop machine.
5. Finally let's see what happens on the integrated video market:
Intel released the GMA X3000 which could perform much better than its predecessor (4 pixel pipelines, 2 vertex pipelines, DX9 Shader Model 3).
Sadly the drivers are not really optimized yet, this way the new GMA's gaming performance is poor, but it can become better with new driver releases.
ATI started to manufacture the 690G integrated VGA (this is a half X700 with 4 pixel pipelines, no vertex pipelines, and only DX9 Shader Model 2).
I can't really recommend this product.
Nvidia will release the 7050 on the integrated VGA market, I don't know about the specifications yet.
I think IGP's will never reach the ,,horsepower" of budget dedicated VGA's, because who would buy an ATI X1300 or an NV7300 if the performance level were equal?
Good luck for making your choice, hope I could help a littlebit. (:

Your Intel GMA don't have vertex pipelines, so all vertexes are calculated by the CPU. When you are alone on the track, maybe you can get acceptable performance, but when other cars appearing, the gameplay becames choppy.
Sadly, unlike ATI's X200, the Intel graphics processor don't have Hardware Transform&Lighting capabilities... big performance hit.
(A little half-off topic: with Riva Tuner I ,,made" an integrated 6100 equal card /425 MHz core frequency, 2 pixel pipelines, 1 vertex pipeline/ from my nV 6200TC VGA card. The result is: with an AMD Athlon64 3000+ CPU, I can get at least 30 fps with 20 cars on the grid. Turning off the remaining 1 vertex pipeline caused 50% performance drop.)
Does your motherboard have an AGP or PCI Express slot? Even a really budget VGA card (for example: ATI X300, nVidia 6200) could bring you more enjoyable gameplay.
But if you don't want to spend money, here are some advices:
-Turn down the ingame screen resolution to 800x600, and apply 16 bit color depth,
-Than turn on the ,,Screen width affects LOD" option -this will reduce level of details if the resolution is under 1024x768,
-Turn on track LOD reduction,
-Turn on the ,,Simple track - no car shadow" option,
-Turn on the ingame frame limiter (set the value to 35-40 fps). This way the CPU won't have to calculate the maximum possible fps -you'll have more balanced performance.
-You can try the wheels view -maybe not realistic as sitting in the cockpit, but the graphics processor won't be overloaded with calculating the nice interior of the car,
-As mentioned before, it is very useful to turn up the dynamic LOD reduction (at least a value of 0.50. is recommended).
Hope I could help a bit.
