Hack number 2 for testing

Ok, just as I expected we suddenly don't put buffers into VRAM any more and=
 the
UVD block has an undocumented requirement for WMV playback that those buffe=
rs
needs to be in VRAM.

No idea why user space is broken, but the kernel should catch such cases and
force them into VRAM when the hardware needs that.

Please revert the last hack and try this one. It should only the first and
second buffer into VRAM.

If that doesn't work try to change the if so that the first,second and third
buffer are forced into VRAM etc....

I need to know which one is needed in VRAM here.
