Extra information. Since today I have added

     Option "Shadow" "true"

to the device section in xorg.conf and since that, the artifacts and visual glitches seem to be gone, and I have yet to see the X server freeze.
Of course this is not a solution, but merely a workaround. I have virtually no form of acceleration now.
