Now, it's easy enough to just turn off CONFIG_X86_CMPXCHG64 (it really should be "8B" instead of "64", but that's another issue) for those things, and nobody should really care, but still, maybe we could re-do the early bits to be more polite to those VIA CPU's? I thought the cmpxchg8b stuff was just used to page table setup. Do those things even _support_ PAE? What else uses it? Early setup in real mode? What am I missing? My grep powers are waning..
