You've got to be fucking kidding me.

Well ... that seems to answer it.

I guess I'll put two kernels on, a UP kernel and an SMP kernel.  I can
boot the UP kernel for normal use, which will allow me to suspend, and
I can boot the SMP kernel if I want the extra CPU, or if I have time to
help debug the problem.

Thanks a lot for the input.
