+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...

That's either the first or second thing I tried.  As far as I can determine,
any invocation of 1.6 with the FASTROM switch on munges Dyna-Show.  

Go figure, eh?
