Intel High Definition Audio on Intel P945pvs Motherboard Not Recognized

[Eric Heintzberger]

I am trying to get sound working using an Intel 945pvs
motherboard with onboard ICH7 "High Definition Audio".
It is my understanding that this should be possible
given the recent advances in support for ICH7. 

I have tried unsuccessfully with FreeBSD 6_0, various
6 stable builds, and  most recently with 
6.1-PRERELEASE. In most cases, I just use the kernel
modules, putting 'snd_ich_load="YES" ' into
"/boot/loader.conf". Kldstat indicates both "snd_ich"
and "sound" loaded successfully, but no driver
attaches to the device according to "pciconf -vl":

none0 at pci0:27:0: class=0x040300 card=0x07078086
chip=0x27d88086 rev=0x01 hdr=0x00
    vendor   = 'Intel Corporation'
    device   = '82801G (ICH7 Family) High 
                Definition Audio'
    class    = multimedia

I have succeeded in attaching the driver by manually
manipulating the chip numbers in files like such as 
"/usr/src/sys/dev/sound/pci/ich.c", and then
recompiling the kernel. This was ultimately
unsuccessful, as "cat /dev/sndstat" still showed
nothing. 

I have also tried some of the new patches from
http://people.freebsd.org/~ariff/, but none of these
even get the a driver to attach to the sound device. 

In no case was I successful in getting FreeBSD sound
from this relatively new motherboard.

Any help would be much appreciated!
