machdep.hyperthreading_allowed does not affect SMT cores

I have a Intel Sandy Bridge system that reports that it has SMT cores
instead of HTT(under a derivative of FreeBSD 8.2).  I'll admit that I
don't at all understand the distinction between the two -- I thought
that HTT was just Intel's name for SMT.  In any case, is there any
reason that machdep.hyperthreading_allowed should not apply to SMT
cores, too?
