That would be nice, as i may also get one of those soon (they should
cost around 100$-125$ which is very cheap for a board which basically is
a 8500).

Well, if i understoof right, these board will use the pixel shaders for
this kind of stuff and maybe other stuff as well, sort of like
programable video accel, so it may be easier to get these things into
the XFree86 drivers, even if there is no specific doc for those
features available (after all, the pixel shader language is documented,
i hope, and you just would need to program the decoding/accel part in
this language).
