I intend to yes :-) Along with my WIP pata_macio of course but I don't
like leaving a driver broken and/or non bisectable, believe me.

Thanks, I will. I've been busy with all sorts of other things so no, I
haven't looked yet, and it's a bit less urgent, but thanks for the
pointer,

Sure but the fact that mediabay calls them directly makes it painful to
deal with 2 drivers, one using drivers/ide and one libata. So I want to
turn that into a notification into the low level driver so it does what
is appropriate.

Sure. I don't think I will need to change any of the core.

I'll let you know when I get something done.
