>From a quick scan of the ICH6 Programmer's Ref, it appears that in at
least some respects, this chipset is compatible with the ICH4 chipset,
among others.  From Intel Doc #30234903:
	The ICH6 AC '97 controller is fully compatibility with the
	features found in the ICH1/2/3/4/5 versions. This allows for
	current drivers developed by ISVs and IHVs to work without
	modifications (see Section The ICH6 however, provides
	new capabilities not found in some of earlier ICH family of

So I'll bet that if you taught the driver about the PCI IDs, it would
probe successfully as an ICH4, which I know is supported.  Not having an
ICH6 I can't test it here, but the change should be relatively trivial.
