The attached 3 patches serve the following purposes:

1. Make the i810_audio.c driver working again. Well it's tested on my 
private hardware.

2. Make the bttv driver work again. I know that there is a GREAT REWRITE 
of this
  driver underway, but still it's a bit annoying to miss the TV until 
that's ready.

3. This is just fixing an obvious mistake from the final release and let's
  the whole compile at all on IA32.
