ATI x800, radeon driver and libreoffice nightmare

[s91066]

Hallo,
I have a huge problem with my Libreoffice/ATI combination!
My setup is:

• openSUSE 11.1 Evergreen, 64bt, updated with the latest patches
• LibreOffice 3.3.2
• ATI Radeon drivers on X800 AGP card

When I work on the LibreOffice writer, I "experience" random freezes. Mostly when I do some "redesign" on the LibreOffice layout, or scrolling... X is not responsive anymore, keyboard is not working, only the mouse pointer works (not the click events). I cannot change desktop, go to the console or generally work with my keyboard...
The only way to make my PC working again is by SSH on it via another computer and execute a "shutdown -r -f -n now"=forced shutdown. No init 6, or reboot, or init 3 works.
From top I see that X takes over 99% of CPU. I tried to kill xorg, but all I managed was a defunct xorg process still taking over 99% of the CPU.
Note: The screen is not changed if I kill -9 the xorg! I still see it, and of course, keyboard is not working etc...
Does anybody have an idea about how to solve that?

Note that I have the following entries in xorg.conf:

Section "Device"
  BoardName    "R420 JJ"
  Driver       "radeon"
  Identifier   "Device[0]"
  VendorName   "ATI"
  Option       "TripleBuffer"
  Option       "AccelMethod" "XAA"
  Option       "EnablePageFlip" "true"
EndSection

and I have tried the bare minimum:

Section "Device"
  BoardName    "R420 JJ"
  Driver       "radeon"
  Identifier   "Device[0]"
  VendorName   "ATI"
EndSection

You probably should try running in PCI mode rather than AGP mode. Not sure what the current way to do that is - used to be Option "AGPMode" "-1" in xorg.conf but with KMS it might require booting with radeon.agpmode=-1 or something similar.

Does it make a difference if you start LibreOffice with LIBGL_ALWAYS_SOFTWARE=1 set?
