The way machdep.hlt_logical_cpus works is by telling the scheduler to ignore the extra logical processors, not by pretending that the extra logical processors don't exist at all. (This was necessary to ensure that interrupts could still run on the extra threads -- otherwise some problems appeared with broken BIOSes which couldn't route interrupts correctly.) If you look at top(1), which processors do you see actually running processes?
