So the reason you were having your problems seems to be your CPUID
isn't included in the family_67x whitelist of CPUIDs. No compiled in
CPU driver claims your cpuid, then it just dies.

Hmm... You have the same cpuid as mine. Interesting.

Anyway, That line you edited should have been removed altogether as
that register was already set elsewhere. I submitted a cleanup patch
for this and don't know how it end up. BTW enable CAR and try again.
We want to officially migrate the ASUS P2B family to CAR.

Cheers
