[Bug 580110] [NEW] ATI Radeon X200M fails to initalise correctly on kernel 2.6.32-22

[CB]

Public bug reported:

When the system is started up on kernel 2.6.32-22, as soon as the login splash screen is shown the graphics become a complete mess, to the point that what is shown on the screen bears no relation to what should be being shown. I know that the login screen is being shown because I can hear the sound telling me the system is ready. I can login blind and hear the login success sound but the graphics stay a mess. Attempting to switch to a text console(CTRL+ALT+1) causes the screen to change, but the graphics are still the same mess and still do not correspond at all to what should be being shown. This problem never occurred on 2.6.32-21, which I am currently using. The problem also used to occur intermittently on older kernels (2.6.2x-xx's). With these older kernels changing resolution or graphics mode(some full screen applications) also used to cause the problem.
I have a Dell Vostro 1000 laptop with Radeon Xpress X200M graphics. The problem occurs with both the internal LCD and an external VGA monitor.
I am afraid I cannot run apport-collect or provide dmesg, uname -a, etc. output as I have no coherent graphical output while running under the problem kernel. I have attached lspci output while the system is running under 2.6.32-21.
