Mmm... not sure if this will answer your question but as I understand, HT
is the hardware part while SMP is the logical/software part you need to
"double" your microprocessor. You need from both to get the job done so
when you disable HT in BIOS, is the same that if you had installed a non-
SMP kernel.
Wel, sort of :-)
