I just tried installing openSUSE 12.1 on an old compaq presario 900 with a broken TFT panel and have exactly the same problem. Setting register 0x0284 does not work, and shortly after reloading radeon with modeset=1 the system hangs. Is there anything else to try?
The attached diff compares the register values when modeset=0 (working) with them when modeset=1 (fail).
