Configuration: emachines T3624 [VGA compatible controller: Intel Corporation 82845G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device (rev 03)]. Kernel 2.6.31-20-generic
Status update: Put testing aside for a time pursuant to a stable platform via the following "work-arounds": 1) Created simple xorg.conf to select vesa driver. Acceptable performance with marked stability improvement (i.e., no freezing). Note: Used "Xorg -configure" to generate baseline xorg.conf - Xorg failed to start using this file. After a bit of "cut & paste" all was well. 2) Installed xserver-xorg-video-intel-2.4 per the instructions of ReinhardTartler (https://wiki.ubuntu.com/ReinhardTartler/X/RevertingIntelDriverTo2.4). Screen was improperly sized/positioned during startup. Included Modeline and Option "PreferredMode" in xorg.conf. Startup issues resolved, performance acceptable, no freezing. 3) Installed safe configuration per the instructions of pyske83 (http://ubuntuforums.org/showthread.php?t=1130582). Added device options (including "Tiling" "false") to the xorg.conf file of item 2 above. No startup issues, acceptable performance. Selected GLMatrix screensaver which ran over 12 hours w/ no freezing. System has been running over 18 hours w/ no freezing. Glxgears performance: glxgears frame update rate was 125-150 fps for all of the work-arounds cited previously. Previously, the glxgears frame update rate was 280-300 fps. Note: psyke83 (see reference) urged caution regarding interpretation of glxgears performance metrics. Note: During my research I read numerous forum and/or mailing list entries from individuals stating that they had or were about to abandon Ubuntu Linux because of this issue. Clearly, this malfunction should be rectified and hopefully these findings will be helpful to those more informed.
