The relevant part of dmesg with Daniel's patch

Daniel's patch not works for me. I tested with 3.1 kernel, and I saw only some
dotted line and a cursor when Xorg loadaded. (Attached the relevant part of
dmesg.)

Current state of the driver with the 3.1 kernel:
- Still get random GPU hangs without ShadowFB. It works stable with ShadowFB.
- XVideo: contrast and saturation are misconfigured (Bug 42488)
- OpenGL without ShadowFB: it's fast and stable until a GPU hang. Once GPU hang
occurred, OpenGL apps are no longer works.
- OpenGL with enabled ShadowFB: it works, but very slow, slower than llvmpipe.
- Trying to run GNOME Shell always cause an immediate GPU hang, even if
ShadowFB enabled.
