The distro's i386 SMP kernel detects only one processor.

Its a custom built box, I dont have the mother board manual with me at
this instant. It uses a IWill 8-way motherboard.

I dont have the permission to remotely login as root at this moment. I
will have access to the console in the morning. I can boot the machine
with acpi=off and try it.
