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.

Thanks for your efforts!
