I'd like to see a HW decoder (Mpeg 1/2/4), S-Video and
DVI out for 720p and 1080i on a graphic card with an
open source driver supporting this decoder.

The question is: will this ever happen?

The main problem is: you need CPU power and therefore
you'll get a system which can not passive cooled and
even a low noise cooling is a big problem.
