I applied the patch, and got all the same output on my MDD as in your email, but
there is no /dev/pcm0.  I do have a /dev/sndstat, and /dev/mixer0.  The
following is the output of /dev/sndstat:

FreeBSD Audio Driver (newpcm: 32bit 2007061600/powerpc)
Installed devices:
pcm0: <i2s> at i2s [GIANT] (1p:1v/0r:0v channels default)

And my dmesg:
