The lack of the following seems to indicate that you do not have "device 
apic" enabled in your kernel config (You need "options SMP" as well to get 
FreeBSD to do more than just recognize both CPUs):

FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs
  cpu0 (BSP): APIC ID:  0
  cpu1 (AP): APIC ID:  <some number>

Please share your config and the steps that you are taking to build your 
kernel.

Cheers,
Andy
