Hmm, that's a strange one.  If you give the command:

	SetCPU FASTROM CACHE NOSTACK

you should get arbitrarily close to the setup you would have with SetCPU V1.5,
eg, plain old FASTROM (no patches), data and instruction caches turned on.
The other difference is that SetCPU V1.6 flushes all I, D, and sometimes
address translation caches when you run it.  That's a pretty weird on, in 
any case.  I'll let you know if I think of any other obvious differences...
