Well, I guess I could do that, but from what I can find, the snd_ad1816 
driver is for the Analog Devices AD1816, which is an obsolete sound 
controller that ran the AC97 audio.  The stuff in the Striker Extreme 
has compatibility with the older AC97 stuff, but only at the cost of any 
of the hda improvements.  I would only do that if there was no onter 
course.  I went to the Intel developers site, and picked up a couple of 
good (if large) pdf's describing the HDA PCI register architecture.  I 
went to the Analog Devices site, and they had a fiar pdf, describing the 
layout of the AD1988b device, which is a lot of the implementation of 
that HDA architecture.  I can't tell  if it's all the implementation, 
yet, because I haven't been able to locate anything on the Nvidia 680 
chipset, and that might implement some of the sound also.  BUT, the fact 
that I can't find anything from Nvidia about what they designed for 
sound might mean that their entire implementation is the AD1988b device.

Do you know more?

Where do the developers of the HDA code hang out, on this list?  Is the 
snd_hda the current hda driver, and if so, where's the new code going to be?

God, maybe I better let my questions lie quiet a bit.  I get too many, 
and you'll never answer any of them.
