[PATCH] CPUID bug and inconsistency fix

The recent support for K8 multicore was misported from x86-64 to i386, due
to an unnecessary inconsistency between the CPUID code.  Sure, there is are
no x86-64 VIA chips yet, but it should happen eventually.

This patch fixes the i386 bug as well as makes x86-64 match i386 in the
handing of the CPUID array.
