I know it is another chip than bktr now... My chip has product id 0x8811
for the audio part rather than 0x8801 as per NetBSD's pcidev. I noticed
because I was used to seeing

with my patch, but booted from a NetBSD install CD to see

So, first got excited that it was recognised, and then wondered about the
lack of audio decoder. (0x8811 and 0x8801 both do that job)

Cheers,

Patrick
