I don't think it is.  I did it a while back in order to simplify the
memory map.  We've already required some kludge to that because Apple
added back some hardcoded I/O addresses to the ROMs (some ROMs got
VIABase from low-memory globals--some earlier and later ROMs hardcode it).

Hmmm...  I don't have the memory map around anymore.

If loading drivers off nubus cards and utilizing the ROMs more is the
direction that we want to take, moving I/O and nubus back to their
normal habitats is probably necessary.  At the time I moved them down,
I was of the opinion that we didn't want to go that route (but rather
wanted to access the h/w directly--as impractical as that is, there are
fewer unknowns that way...  If you're loading drivers off a card and
running them, it's kind of a "call and pray" methodology ;-).
