Patch applies cleanly and builds with 1.0.14rc1, and macpro model
selection works.  The dmesg dump is attached (though it's pretty terse).

Great news: I have the correct volume!  Here are some mixer oddities:

- The "Surround" mixer channels actually control what comes out of the
line-out jack on the back of the Mac Pro (where I have my speakers
plugged in).  This was the case before.

- The "Front Mic" mixer channels actually control the line-in jack on
the back of the Mac Pro (where I have my radio's line-out plugged in).

- No combination of mixer channel volumes and "Headphone" switch setting
seems to control the headphone jack on the front of the Mac Pro (can't
get any sound from it).  Not a big deal for me, but might be for others.

- The "PC Speaker" mixer channel doesn't control the internal speaker.
I don't know if this is actually possible in OS X (don't have it installed).

Also, I don't have an optical cable to test the digital in/out.  Have
not tested the other analog channels (don't have a mic, etc.).

Thanks for your work fixing up the driver for the 885.
