I dont have a sparc to test on.  (the other changes are straighforward
enough that I could verify them with cc -E output :).

Also, afaik, the indirect registers may need to be written as two
separate bytes, and at least the pmax requires some delay between the
byte accesses (which arent required for the ioasic bus in general).
Is tthe w16 hook is necessary there anyway, or do we derive a new
bus in cases like that? urgh.

Anyway, can someone add a bus-space tag to the attach args, make the
obvious substitutions to the patch I posted, and try it on a Sparc?
Or should I give up on this for 1.4?
