If I made it myself, then all I'd need to know then is...
1. Where can I find a quite high-res logo...?
2. What's the font used for the number as well as the S2 part of the logo as shown on the screenshot?
Heres the best one i have got. Not the big but should do. Also the font looks like it could be Agency fb (i think its called) Just scroll through all your fonts till either you find one you like or one that is similar.
Here's the original plate by g30rge (I bet if/when he gets back he's gonna kick my ass). The font is called 'Eurasia'.
EDIT: If the resolution isn't high enough for your use, it isn't that hard to draw it yourself. To get a big LFS logo, just press 'print screen' button when starting LFS, and paste the image to your favourite editing program..
