I've put it on hold for modularisation and memory manager work as it would
be much easier to get this done with some sort of memory management..
I don't really like the idea of reserving chunks of VRAM on the off chance
someone might use it..

I have enough information to write the lowlevel XvMC driver its the higher
level DDX setup code that is holding me back a bit..

Dave.
