Re: Any Radeon HD testers?
ATI Radeon HD 4670 here - I switched to the open source driver to see if Plymouth would display correctly at startup. At the time I was not aware of the power management bug. I experienced temperature problems and crashes on my desktop PC, particularly when using gimp and watching a video / TV at the same time. Problems solved by switching back to proprietary fglrx.
I would take the above view from djchandler seriously!
If using open source video drivers check your hardware temperatures and it should be noticeable that your fans are spinning at very high speed anyway. My PC case developed a resonant rattle!
IMHO using the current xserver-xorg-video-ati driver could be putting your hardware at risk
I have not tried this yet:
In short try radeon.modeset=0 or pci=nomsi as boot parameter.
