Mat, I've separated/unified all the patches, both can be applied
cleanly on HEAD / RELENG_5 (hopefully). Take a look again at
http://staff.mybsd.org.my/skywizard/FreeBSD/sound/
I guess the most important thing is to address the panic issue
(mixer.c.diff / sound.c.diff) and sluggish fixed rate ac97
(vchan.c.diff). There are also other issues, such as MPSAFE (those
pci/ diffs), ac97 volume resolution detection (ac97.c.diff), and
I still consider it as a top priority too. Considering our current
state of sound driver, I don't mind if it breaks other people (that
should help us progress, I think)
