The problem is that due to the entertaining nature of AC'97 support in
Linux we don't actually have anything to free at this point - we'd need
to redo the whole infrastructure, not just this code.

You really need to find someone with an ongoing interest in AC'97 and
convince them that it's worth overhauling the bus, the whole thing is
just too much of a can of worms to touch.  Fixing this for 3.3 seems
completely insane, we're already in the merge window and there's too
many skeletons.

I'm not even sure I have any AC'97 hardware any more myself.
