I believe I have a branch with macio QOM'ifications somewhere that I
could revive. Note that I know little about IDE or block layer and
mainly care about consistent infrastructure there; I vaguely remember
something about the mac's IDE channels being mixed together from two
devices unlike real hardware, guess I would be unable to fix that.

As for your question, 2013 and a gentle reminder to all involved would
be nice. :) In particular we have the Soft Freeze coming up shortly
after the holidays, so is this needed for 1.4 Soft Freeze or can it be
deferred to 1.5 or done during the 1.4 Soft Freeze?

If Aurélien (CC'ed) doesn't manage, I can look at r2d as well.
CC'ing Peter and Andrzej for the arm devices.
