Thanks to all who responded. The actual problem/solution was identified by
Nick Hill, Dave Cherkus and Benoit Maillard.
There is a console variable, cpu_enabled, similar to the variable,
cpu-enable-mask, handled by sysconfig. The console variable was set
to enable only one cpu. I don't know how the console variable got set
this way; whether it was magic because i'd set the sysconfig variable,
or someone else made the change.

Here is Dave Cherkus' response which worked like a charm:
Try:
P00>>> set cpu_enabled ff
P00>>> init
P00>>> boot
Most folks don't do the init...
If UNIX shows lines that start with:
cpu0:
cpu1:
in the boot sequence then you're OK...
