Change <b28> to HTT (Hyperthreading technology). If this flag is set then
cpuid with %eax=1 will return a logical cpu count in bits 16-23 of %ebx.
Bit 29 is actually 'TM' according to AP-485. This signifies the presence
of the thermal control circuit (which I believe can slow the clock down
to reduce core temperature).
