I am sorry I gave up on nouveau and Unity due to the very poor stability except in Unity 2D mode. I am now using the nvidia drivers after needing 3d accelleration to run VMeare. Once i switched back to Gnome shell as well I have found it to finally be as stable as 11.04. To be clear Unity 2d, Unity 3d and nouveau all seem to have stability issues on this hardware (mainly nouveau). With Unity and Nvidia the kernel issues do not appear, but Unity itself seems to have some stability issues that I have not seen while running Gnome shell/nvidia for about a month.
