I can repost it but a split would be very hard. I prepared a patch to 
just add a new driver inside alsa-kernel. The old one from the
alsa-driver could be removed then. The diff between the new and 
the old driver is over 140KB - only headers are not changed much.

I have tested audio (PCM) playback and recording (hence
pcm format bugfixes). I have tested MIDI playback (through
built in wavetable). I have not fixed more exotic features like
digital output/input and external MIDI handling (no device
to test). I think that the basic support (pcm playback/recording
and midi playback) is enough to add the driver.

Can I repost as a single patch?
