Today I've tried to checkout RELENG_6 kernel source and rebuild snd_hda.ko
and sound.ko on my 8.2-STABLE. snd_hda(4) required almost no hackery,
builds and loads fine; mixer(8) reports something sane now: `pcm' and `vol'
volumes (compared to just `speaker' and `rec' before).
Alas, while it looks fine, sound still does not work. Apparently, old
snd_hda(4) does not play nice with new sound(4). However, it seems that
HDA-related logic at least detects and setups my sound chip correctly.
I've tried to build sound(4), it required some manual patching to fix all
unresolved symbols on module load (CHANNEL_SETDIR, msleep, minor, sx_init).
However, once it loaded, laptop paniced immediately. :-(
