Let me add: 

Motorola MTX (and probably dual CPU MVME boards) have early (working)
support for SMP. Dual CPU have two 604e chips running at 300, 333, or 400
mhz, fyi.

Support for the MTX isn't fully complete, the MTX board I use is
reasonably stable. It will, however crash with more than 2 or 3 large
compiles running.

PowerMac SMP is similiar to standard PowerMac. The MTX booting process is
somewhat involved, and the MTX SMP code is not in the mainline kernel yet.

Do you have any suggested benchmarks?
