Looking at the 2.6.16 sources, it appears that CONFIG_CPU_GENERIC sets
all the cache size options of CONFIG_MSPC (em64t), and the only other
difference is that CPU_GENERIC doesn't set -march at all.  So if
-march=k8 doesn't break em64t then it should be fine, well assuming the
cache size entry doesn't matter either.

So from what I see:
CONFIG_K8: CACHE_BYTES=64, march=k8
CONFIG_MSPC: CACHE_BYTES=128, march=nocona
CONFIG_CPU_GENERIC: CACHE_BYTES=128, march=not set

So does some expert on the instruction set know if the march is a
problem?  I imagine the kernel packagers know and hence know what they
are doing with dropping generic. :)
