We have that problem with mga_vid already, but as X and mga_vid
are accessing different memory regions, that's not a big issue.

The only real issue i see is, that during a DMA transfere,
MPlayer has either to sleep until the buffer is coppied or
that the codec has to use a copy of the buffer to work on.
Both options are not very exciting.
