One cannot tell from the text that you pasted. Look for the following 
message to be printed out in a boot -v:

FreeBSD/SMP: Multiprocessor System Detected: 4 CPUs
  cpu0 (BSP): APIC ID:  0
  cpu1 (AP): APIC ID:  1
  cpu2 (AP): APIC ID:  2
  cpu3 (AP): APIC ID:  3

I have a boot -v and a kernel config for a dual-proc athlon up at:

Under SMP, there's a "C" column that shows up:

  PID USERNAME PRI NICE   SIZE    RES STATE  C   TIME   WCPU    CPU COMMAND
2782 root       5    0  2080K  1448K ttyin  3   7:35  1.95%  1.95% systat
