ICH7 supposed to have new Intel High Definition Audio (HDA), which
unfortunately isn't supported (yet). I'm not quite sure whether it is
backward compatible with AC97, but you can try your luck hacking the
driver (/usr/src/sys/dev/sound/pci/ich.c) by adding the appropriate
pci id into ich_pci_probe() function. pciconf -l (chip=xxxx) should
give you the appropriate value for that.
