Color tiling is broken on my RV770; I've bisected this down to this commit:

    Fix KMS on big endian machines.

    Requires at least xserver 1.7 to work properly.

    Also make sure the front buffer is and stays tiled if colour tiling is
enabled.

I'm using Xorg 1.7, with DDX, libdrm, mesa and kernel from git. The driver
works fine when ColorTiling is disabled in the configuration.
I'm attacching the log with tiling enabled and a photo of the monitor (with
just an xterm).
