we've already bumped into this, some motherboards with intel hyperthreaded processors have a bios mp table and some don't. when i started the amd64 port i decided to not bother about the mp stuff for the moment and once it was working then do the mp stuff anew (it is ~10 years old and crufty) and not rely on the bios. i'm about ready to do that now and it should cover both intel and amd processors.
