Comment (by cjb):

 Replying to [comment:8 dilinger]:
 > Does the quirk need to happen before the call to snd_ac97_mixer?  If
 not, let's combine it with the other (post-snd_ac97_mixer-call) quirk.

 Yes, that's why we needed to create a new quirk function.  This quirk
 needs to happen before mixer(), and the other quirks need to happen after
 it.

 > Also, Mitch tells me that we need to clear the EAPD bit prior to
 suspend.  It looks like ac97 already does this if AC97_SCAP_INV_EAPD-
 related things are set.  It would be nice to piggyback off that
 functionality if we can..

 That sounds promising.
