You can probably hack your way around this with something like the following patch.
I'm now running kernel 3.2.1 and tried the patch you gave but it didn't seem to help. I'm an ALSA newb but I've CC'ed Mark Hills (of xwax) who knows more about it. If you'd be so kind as to let us know more specifically what we should do, we would be very grateful.
FWIW, the manufacturer just sent me another device with supposedly fixed firmware, but I still get the following when I plug it in:
