Yeah I know about one.

DRI allows for locking the box. I can lock the radeon, I can lock the
matrox. Its supposed to not allow worse than that. The XvMC slice
registers for mpeg are all in one location - is that too close to other
registers to split up the map ? If not perhaps the slice load should be
in the DRI module ?
