Yes, I think this driver's device probing is starting to improve the ID
table approach that we currently have, which is why I directed a few
comments at it. I don't think it goes far enough to being useful to
others yet, though. It employs a few hacks that tie it very closely to
its own implementation, and I think this can be improved now, before its
methods are entrenched too much.

No, I don't think a generally-useful framework will pop up overnight,
but I think this driver can be one piece of the puzzle.

I await your further responses.

Thanks,
Brian
