Ugh, this is supposed to have a unique identifying value. Did
you get a very early board from Intel?

You can check. However, I've looked at the BIOS updates that appear
to have no changes related to the HDA config default regs. My
current patches load up the appropriate config default values but
I currently have an issue with reliably identifying the appropriate
board for each set of values.

You'll also need the patch update to get the retasking controls.
 
I'm working with SigmaTel on this so let me check on some things
regarding board ID and then I'll hopefully have a patch to post
that will work for you.  We may have to resort to manually
specifying the model type for these boards...I'm hoping to
avoid that though.
