You want the stepping to be the same.

You may not be happy with P III's.  I'm not sure if the SMP code
has been changed to handle only the xAPIC now, or not; there was
a discussion a little while back about supporting more than 16
CPUs in a machine, which would require this change.

I know that my Dual P90 machine has been unable to run -current
for quite some time due to some changes that went in to the low
level mp_machdep code.
