Sorry, my "i386 compilation testing" was to do an allyesconfig, disable
CONFIG_64BIT, then compile…

This — now I embarrasingly discover — does not enable the kconfig options
that depend on X86_32=y; e.g., the CONFIG_AGP_EFFICEON case above.

It seems that, kinda like cross compilation, an "ARCH=i386" environment
variable should do the job well with allyesconfig and the rest.

I'll make sure that all future CPUID work passes that step before sending
it mainline.

Thanks a lot,
