No.  It has to do with the manufacture of the cpu.
I won't claim to understand it, but the stepping
must be the same for both of your processors. 
This is why Pentium Pro's were commonly sold in
matched pairs.  If the Pentium processors you
are using are not from the same lot, you'll need
to check their model/serial numbers against
Intel's database to check what the stepping
level is for each processor.  They need to have
the same stepping level for smp.

Yes -- uniprocessor.

Good luck,
