3. 601 processors may barf(?) on some of these instructions.

No, it does not. It's just that the cache is unified which makes most
coherency functions irrelevant.

So 601's have no problems with sync and isync, just eieio?  AFAIK, there is
some code snippet in the kernel that somehow works around a 601 problem
with one of the synchronization instructions but I don't remember which one
right off hand.

There's a bug on certain cards in x100-land that makes them crash on
sync() and eieio().  isync() is irrelevant on a 601, since there's not a
separate instruction cache.

I can only assume that this is what the original poster meant.
