If you have a SMP kernel loaded, here are some indicators:
dmesg will show you just below your memory/apic info
	FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs
	 cpu0 (BSP): APIC ID:  0
	 cpu1 (AP): APIC ID:  1
and 
	SMP: AP CPU #1 Launched!
just before init takes over.
Also mptable(1) will give you actual output.

If FreeBSD does not recognize your SMP configuration, enter your BIOS
and search for an option that sounds like 'MP-Table', 'MP-OS',
'MP-Spec'... depends on your BIOS vendor. Possible values should at
least bei 1.1 and 1.4. I've seen OS/2 and Unix too.
Try them until you find a setting that reports a valid mptable to
FreeBSD. There you go.

If your SuSe version expects a different MP-specification than
FreeBSD, it is normal that while SuSe 'sees' both cpus, FreeBSD does
not.
