I found out that in the Bios of my computer the AGP capability mode was
set to 4x. Indeed, the Radeon 8500 LE supports this mode. However, the
xorg.conf file generated by issuing the command dpkg-reconfigure
xserver-xorg contains following device section:
Section "Device"
Identifier "ATI Technologies, Inc. Radeon R200 QL [Radeon 8500
LE]" Driver "ati"
BusID "PCI:1:0:0"
Option "UseFBDev" "true"
EndSection
I added the 4x mode as follows
Section "Device"
Identifier "ATI Technologies, Inc. Radeon R200 QL [Radeon 8500
LE]" Driver "ati"
BusID "PCI:1:0:0"
Option "UseFBDev" "true"
Option "AGPMode" "4"
EndSection
Interestingly, the glxgears crashes that occured when quickly moving the
glxgears window around on the desktop disappeared. Also, 3D games such
as Tuxracer and 3D screensavers seem to run without freezing my
computer.
However, when e.g. surfing the net with Firefox/Konqueror for a given
time, my computer still freezes hard after some time. As mentionned
before, this seems to be related to another bug, maybe due to the
wireless (atheros) madwifi driver or the network-manager I use.
