I talked further with Alex about this bug and the mis-mapped registers. He gave me a list of patches he felt that would be high priority for addressing the various issues that may cause Compiz to lock up, particularly on newer 3xx architecture cards. I've packaged up these fixes into a deb to make it simpler for people to test:

I would love to hear if these patches solve the drmCommandWrite() freeze for 9600 cards. Please give it a test and let us know.
