Default Bug#685895: firmware-linux-nonfree: Intermittent black screen on ATI Radeon with nonfree firmware

Package: firmware-linux-nonfree
Version: 0.28+squeeze1
Severity: important

I have an old computer with a Radeon 9200 (RV280) AGP card.

After installing Squeeze everything works fine. If I install firmware-linux-
nonfree to get the firmware for my Radeon card, the screen (in X/Gnome) goes
black for a second or two and then returns to normal. This happens mostly when
the screen is updated, e g if I scroll a window, several times per minute if I
actively use the computer.

If I remove firmware-linux-nonfree the problem goes away, but GPU acceleration
is disabled.

I tried using a newer kernel (linux-image-3.2.0-0.bpo.3-686-pae) and firmware-
linux-nonfree (0.35~bpo60+1) from backports, no improvement.

Since I do not need any other firmware from the nonfree package I can remove it
as a workaround. Others might not have that option.
