| I'm wondering about the ac97 codec message?

The ac97 code has a table of codecs that provide the name and optionally a 
function pointer to a vendor specific initialization routine.  On RELENG_4, 
the AD1985 does not have an entry, so the codec is indicated as "unknown" with 
the relevant codec id.  The latter is useful for diagnostics.

If you want a short-term fix you can edit the codec table in 
${SRC}/sys/dev/sound/pcm/ac97.c.  We're about due for a syncing of the ac97 
codec between RELENG_4 and HEAD, which would fix the message for this and 
quite a few other codecs.
