It works perfectly as a module, indeed: if I do full "make kernel".  I use
modules whenever it's possible in fact.  The problem is that once I rebuild
(in exactly the same source base) just snd_hda(4), that is "cd /sys/modules
/sound/driver/hda && make", I cannot load newly built ./snd_hda.ko anymore,
while "kldload /boot/kernel/snd_hda.ko" works fine.  On the same running
kernel, against the very same sources.

I needed sound to work very soon this time (upcoming Skype conference call),
so I just rolled back your changes and did "make kernel", but honestly I
find it very annoying having to rebuild entire kernel when just snd_hda(4)
rebuild should suffice.

BTW, any ideas why my nid patches from pre-r236750 no longer apply?
