From: cg <cg@FreeBSD.org>
Date: Sun, 6 Jul 2003 03:11:06 +0000
Subject: * add support for amd-768 audio, as used on many dual athlon boards. 
 only tested for playback.

* modify device name strings for ich chips to better conform with their
common names.

* remove superflous 'AC97 controller' from nforce device names.
