The underlying problem is that the newer libata rewrites the dev->id data
in ways that we can't then patch up. I've actually been hacking on this a
bit today. The existing it821x code was working fine and it does the
needed patching, it just needs to do it in a different place, and that in
turn needs a new ap->ops->read_id() method so it can be hooked.

On the bright side that also allows us to implement a pata_mfm/rll
driver at last.
