Inside a program use:
	sysmp(2) with the argument MP_NPROCS

This will tell you how many processors are physically configured. 

It is also possible that you have cpu two boards but they aren't recognized by
the kernel at boot-up. I've seen this happen occasionally, it usually disappears
for me if I reboot.

Hope this helps.
