You said you did a kernel recompile, so did you include
'device		acpi'
'options	SMP'
in your custom kernel before you recompiled?

That is what did it for me.

Do a 'dmesg | less' and near the top portion you should see a statement 
like 'FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs' and then 
after showing the cpu info.

Like someone else mentioned, I also thought ACPI had to be enabled.
