[Jeff250 <jeff250@xxxxxxxxx>]

Robert, I have been using the latest maverick kernel for about 24 hours
now:

$ uname -r
2.6.34-2-generic

I have an Inspiron 1545 and the Intel GM45:

$ lspci | grep -i graphics
00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)
00:02.1 Display controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)

I was previously using the i915.powersave workaround.  To test the newer
kernel, I installed it, and disabled the i915.powersave workaround.  To
ensure that it was disabled, I rebooted into the lucid kernel again, and
the flickering returned--about every few minutes, like before.

Now I've been booted into the latest maverick kernel for about 24 hours
now without seeing any flickering.  Given how frequently I saw the
flickering before, I think that it is likely that the maverick kernel
has resolved the issue.  However, given the flickering's
nondeterministic nature, I will continue using the maverick kernel and
post back if the flickering returns.

Let me know if there is anything else I can do, short of using git-
bisect, to help you track this down.
