I've got something I'm working on for AMD dual-core. Please don't commit
this. We work just fine on AMD dual-core. The patch to disable cores on
Intel Hyperthreaded CPU's does not affect AMD dual-core in one bit. The
author nicely took the different vendors into account.
AMD sets the CPUID.HTT simply for licensing issues - something that does
not affect FreeBSD at all.
If there is something needed for Intel dual-core CPU's with
HyperThreading to use the real cores, but not the virtual cores - then by
all means please commit it.

I do and am working on something.
