I was actually looking at this yesterday, and it seems with some more
testing that only the DBDMA flush part is required. It could be that
fixing the flush semantics prevents the macio device getting into the
incorrect state that makes the macio patch necessary in the first place.
In this case the DBDMA patch should probably go via Alex since it's
fairly specific to the Mac DMA hardware rather than being related just
to the IDE interface.
ATB,
Mark.
