I'd also be interested in responses to that question
since the PPC box I'm porting to has that same VIA
south bridge chip in it and I can't figure out how
to access the IDE command/status registers therein.

It's infuriating since it's clear that a lot of
the pieces are working: I can read/write all the
Config registers (all seven functions worth) and I
have the RS232 controller running and the interrupt
controller routing interrupts, etc, etc.  But the
IDE command/status registers just seem to contain
junk and the driver consequently gives up on it...
