I'm wondering if you have misunderstood the purpose of SMP (symmetrical multiprocessors). That's the architecture of the motherboard. If you want to use the second processor, you're effectively saying that you want to use SMP. An SMP kernel is one that supports them. Possibly you're considering using each processor for different purposes. That's conceivable, but FreeBSD doesn't support it.
