Well, that's what I thought, too, since that was the only file in the kernel
source where CONFIG_MK7 was defined. Somebody pointed out to me, though, that
there are other defines that are turned on if you use Athlon settings, like
(from arch/i386/config.in):

CONFIG_X86_GOOD_APIC
CONFIG_X86_USE_3DNOW
CONFIG_X86_PGE

Although, looking at arch/i386/config.in again right now, I see none of these
are Athlon specific. That's what I get for trusting somebody else instead of
looking into it myself.

Thanks.
