Using the following options caused GPU reset:

        Option     "ColorTiling"    "true"     # [<bool>]
        Option     "ColorTiling2D"  "false"      # [<bool>]
        Option     "RenderAccel"  "false"               # [<bool>]
        Option      "AccelMethod"    "exa"
        Option     "EXAPixmaps"    "True"       # [<bool>]

Whats interesting also is the GPU resets, X hangs (doesnt recover) rebooting
laptop will work but when grub finishes loading the kernel the laptop hangs as
the GPU is in a bad state. I have to hard power off/on for it to work again.

Testing with ColorTiling2D only enabled now,
