Briefly, what happens is the 'X' randomly crashes without warning, and it is
irrecoverable. Any open work is lost. A reboot is required. There is an error in
the xorg.log about rng expecting one number, getting another, then fatal server
error.
Here is the bug report I want to file, you comments are appreciated.

Subject: xserver-xorg-video-intel causes X to crash irrecoverably and without
warning (fatal server error: lockup)
Package: xserver-xorg-video-intel
Version: 2:2.3.2-2
Severity: important
Seemingly at random, and infrequently, X will crash and I will often lose all
open work. After a number of attempts to automatically restart I will be given a
message saying that X has crashed and cannot be restarted. Switching to a
different terminal killing all Xsessions and GDM and attempting to restart them
does not work. A reboot is seemingly required.
Adding the option "NoDRI" to xorg.conf appears to prevent this from happening?
This is not a good option for me as suspend/resume does not work with this
option enabled.
It occurs infrequently, perhaps once every 30 or 40 hours of use, and I have
been unable to find any pattern. I believe iceweasel has been open for all
crashes, though this has occured over an upgrade to version 3.0, and has also
persisted over recent updates to xorg and the intel driver.
The xorg.log seems to contain a relevant and hopefully useful error at the end
of the log.
I set the severity to important because it currently causes a loss of data.
Please advise if I can provide more information. Reportbug was not working for
me and I have filed this manually.
Below you will find my xorg.log, xorg.conf, kernel version, libc version. I am
running Lenny.

AA
