Starting with commit 4e52e8f746e3565bf3fe9ba8e4e3744ce0302478 rendering is
almost completely broken. There are black artifacts all over the screen. 

4e52e8f746e3565bf3fe9ba8e4e3744ce0302478 is the first bad commit
commit 4e52e8f746e3565bf3fe9ba8e4e3744ce0302478
Author: Dave Airlie <airlied@redhat.com>
Date:   Sat Dec 18 10:40:33 2010 +1000

    r300g: add support for color0 writes to all bound color buffers.

    Thanks to Marek Olšák for making my initial attempt actually work.

    Signed-off-by: Dave Airlie <airlied@redhat.com>

Reverting this commit makes the problem go away.

My configuration:
Mesa: 876effb0e717e8e64050662f6ffa286c22065f5c
Kernel: 2.6.36
GPU: RV530

To reproduce you need either 2.2 version of the Unigine Sanctuary benchmark or
2.3 version + patch to enable GL_ARB_half_float_pixel.

libtxc_dxtn.so is also required.
