I have git-bisected this to find that the first bad commit is:
285484e2d55 - drm/radeon: add support for evergreen/ni tiling
informations v11.

So I have also added Jerome to the CC list. Please see the attached
bisect.log for the git-bisect log.

Once again, my card is:

01:00.0 VGA compatible controller: ATI Technologies Inc Redwood
[Radeon HD 5600 Series] (prog-if 00 [VGA controller])
        Subsystem: Dell Device 0447
        Flags: bus master, fast devsel, latency 0, IRQ 47
        Memory at c0000000 (64-bit, prefetchable) [size=256M]
        Memory at fbe20000 (64-bit, non-prefetchable) [size=128K]
        I/O ports at e000 [size=256]
        Expansion ROM at fbe00000 [disabled] [size=128K]
        Capabilities: <access denied>
        Kernel driver in use: radeon
        Kernel modules: radeon

To reproduce, simply:

1. Install Ubuntu 11.04 on a system with the above Radeon card (In
order to get the version of Xorg and DRM libs that I have)
2. Boot and login.

The problem manifests upon login, presumably on that start of Compiz
but I am not sure.
