@mnicky and others: I'm now basically certain that this bug has nothing to do with the "Clocksource tsc unstable" messages; the title of the bug should probably be changed. After I added "nohz=off" to the kernel boot line, the freezes still occurred; others who followed suit had the same results. Furthermore, I've removed that line from the kernel boot line, and have still managed to apparently solved my problem (and right before giving up!).
I solved my problem by following some of the later suggestions found here: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video- intel/+bug/359392. Specifically, I increased my "Virtual" numbers in /etc/X11/xorg.conf, and I applied Albert Damen's debdiff patch. If any of you are using intel graphics cards and the xorg -intel driver, I strongly suggest that you read through that (enormous) bug report, *particularly* if you have the following card (around which that bug report is centered): 00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller [8086:2a02] (rev 03) In fact, that bug report may be a duplicate of this one. I'm not sure how or whether the bug being described here affects non-Intel cards.
