This one (commit a5ee4eb7541) broke OpenGL acceleration on my new test box
which happens to have a RS780.

The symptom is that every operation involving the GPU is _very_ slow, so the
window manager eventually disables compositing. Reverting this commit makes
things work flawlessly again.

So, please revert.

BTW, I don't think it's a -stable material.
