I don't think it will work at all on Intel HT systems, since
nobody initializes c->x86_num_cores there. phys_proc_id[]
is supposed to be the same on two HT siblings.

You'll either need to initialize c->x86_num_cores on Intel too.
But since Intel seems to have dual cores upcomming and you'll
want HyperThreading support too it would need to be a new field.

Alternatively you can split the function for AMD and Intel and
use the new algorithm on AMD only. Perhaps that's better.
In the later case I would only use it when CMP_LEGACY is set.
