Hmm, 604 should do fine.  The FPUs in the 604 and 7xx PowerPCs are not much
different in execution time as that it should be a major problem, I think.

Only that the 604 can dispatch 4 (AFAIK) instructions per clock cycle while
all 7xx except the 7450 can only dispatch three instructions per clock
cycle.  But I suspect the major problem with CodeWarrior is that it doesn't
schedule FPU instructions at all (i.e. interleave FPU and integer
instructions, not even float load/stores), so any improvement in that part
of the code should outweigh the possible slowdowns in the rare case that
four instructions can really be dispatched in one cycle...

PS: In theory Macs should emulate all Power 32 bit instructions.  Of course
it would slow down things :-)
