Your fixes are implemented in another way, so it should work as it is
on 2.6.23 once after alsa.git is merged -- except for (obviously
annoying-for-some-people) "unknown model" message.  I'd say, simply
ignore it ;)  It's no bug.

Yeah, we'd like to go in that way, but it gets stucked right now,
mainly due to lack of development time.  A proto-type is availabe at
	ftp://ftp.suse.com/pub/people/tiwai/hda-tools/
but not sure whether this development will be continued to the final
form or choose another method.
