Yes, but IIRC the one from Christian never made it into mainstream. And the
new one from Krzysztof seems to get quite good reactions.

Yes, both would be way better than the current implementation. Hopefully one
of those drivers will make in into mainline and this should be the one to
pick then.

Yes, just a minor issue from the code point of view, but a big issue from the
licensing point of view.
