     PIO mode is setup by different code, and it takes care of the IORDY
setting according to the PIO rules (and it gets called). DMA mode setup should
just ignore the IORDY setting as in all other sane drivers.

Well it can't ignore it - but if you mean just keep the bit as is then

    Yes, I mean this.

that sounds sensible, have to see what the docs say happens if you ever
set MWDMA without IORDY.

    Don't think they say anything on this matter but I can't imagine that 
IORDY matters for DMA.
