Further information: - An extended 'smartctl' test revealed no errors. So it's probably not the disk. - 'debsums -s' reported errors for a couple of files in OpenOffice; everything else was fine.
I also did some fiddling with options in xorg.conf this morning. Setting AGPMode to 1 does not improve behavior. Setting AGPFastWrites to False does not improve behavior. The system still goes to pieces when GL kicks in. Setting DRI to False improves things -- GL acceleration is disabled, but the system remains stable.
