@Chris, My setup is very similar to markusj's, and I am still having the issue. Unless you can explain otherwise, I would have to agree that you've incorrectly marked this bug as "Fixed Released," when in fact it has not been fixed in Ubuntu 12.04.
@Markusj, Would it be possible for you to verify that using Docky for a little while, and especially while hovering the mouse over it, can recreate the GPU freeze.

The screen freezes except of mouse pointer movement, but the system still reacts on keystrokes.
