Hmm, and this is with a kernel that has 'options SMP' and 'options APIC_IO'
set in the config? Our stock GENERIC is UP only.

Yes that's right, as based on my experience with 2-way Quad-Core Xeon
machines on DragonFly, you have to recompile your GENERIC kernel with
'options SMP' to be able to detect multiple core CPUs.
I see; no this is a stock install kernel.  Thanks.
The LiveDVD contains a prebuild SMP kernel IIRC. In case you are too 
lazy to compile your own SMP kernel :)
