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.
