They are compatible with each other (for the most part at least). I think that the Intel chips don't have as much of a 64 bit instruction set, but mostly just have the ability to handle more memory. I may be wrong though. Anyways, for LFS you can either use x86, which should run fine, or the x86_64/AMD64 info that has been popping up should work as well if you want to build a 64bit system. As far as kernel goes, I think there are some improvements for this chip in 2.6 kernels over what 2.4 contains. Again, I'm mostly guessing off of what I recall from a long time ago.
