audio driver for RealTek ALC658?

[Torfinn Ingolfsen]

I have a MSI RS480M2-IL mainboard (aka MS-7093). According to the specs,
http://www.msi.com.tw/program/products/mainboard/mbd/pro_mbd_detail.php?UID=639
it has a Realtek ALC658 audio codec (and "Compliance with AC97 v2.3
Spec." as the specs tell). Is there a audio driver for this somewhere?

I'm running FreeBSD 5.4-stable (amd64):
root at kg-quiet# uname -a
FreeBSD kg-quiet.kg4.no 5.4-STABLE FreeBSD 5.4-STABLE #1: Sat Apr 16
21:04:54 CEST 2005     root at kg-quiet.kg4.no:/usr/obj/usr/src/sys/QUIET 
amd64

I have tried 'kldload snd_driver', but 'cat /dev/sndstat' still shows:
root at kg-quiet# cat /dev/sndstat
FreeBSD Audio Driver (newpcm)
Installed devices:

Here is the output of 'pciconf -lv' for the audio device:
none2 at pci0:20:5:        class=0x040100 card=0x00801462 chip=0x43701002
rev=0x00 hdr=0x00    vendor   = 'ATI Technologies Inc'
    class    = multimedia
    subclass = audio

and, for good measure, the output of 'lspci -v':
