>Environment:
FreeBSD gneffpc.rtp.dg.com 6.0-STABLE-SNAP010 FreeBSD 6.0-STABLE-SNAP010 #0: Mon Dec 19 15:48:57 EST 2005     gneff at gneffpc.rtp.dg.com:/usr/obj/usr/src/sys/gneffpc  i386
>Description:
sys/dev/sound/pci/ich.c in 6.0-STABLE has no support for ICH7, only up to the ICH6 chipset.  It appears support has been added to -CURRENT, but it doesn't appear an MFC is possible as it looks like a complete re-write.
>How-To-Repeat:
n/a
>Fix:
I've posted a patch here: http://www.trioptimum.com/ich.c.ich7.patch

I've tested it on amd64 and i386, both as a module and as part of a monolithic kernel with no problems.
