why do you think the scheduler will have a major problem? it certainly can be improved for this situation, but i've got an SS10 with mis-matched cpus (2x100mhz, 1x150mhz, the latter with a bigger cache and thus significantly faster than the other cpus) and it works pretty fine. so - my guess is that some of the power and performance issues will still need work, but the system will boot and run normally without special work. .mrg.
