i have smp support compiled into my kernel, an still, i never see anything on
the HT'd cpu. i realize that most ppl believe that the HT portion of the
technology was just a bunch of smoke blown up our butts by intel, but windows
sure loves to bounce that extra cpu graph around a lot. below is just a snip
of my top window, but as far down as i can stretch my 1280x1024 screen, its
all "cpu 0" processes, even while compiling.

dmesg shows that freebsd sees the other cpu...
[root at athena ~]# dmesg | grep cpu

FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs

so is the SMP portion of the technology as worthless as 'they' say?
