Hi again, I've found one component which makes a difference - kernel. When I boot with 2.6.36 (compiled from former radeon-testing branch), everything looks good, when I boot into 2.6.37, I see the corruption. I will investigate the source of the problem and raise a bug report when I know more. The version either is the direct source or it triggers some feature that makes problems.
