Actually, that's awesome! That means that there is a kernel commit
that triggers this bug (this is also the case for some freezes on 845G
and 855GM that I'm troubleshooting. And since you have your standard
Jaunty kernel that works well, you may be able to help identify the
bad commit by testing some other kernels. That would be a very big
step towards resolving this bug.

I assumed you install deb-packages with file names
linux-image-2.6.31-14-generic_2.6.31-14.48_i386.deb and similar to
install the extra kernels. To remove them completely from your
system, run `dpkg -P linux-image-2.6.31-14-generic` and similar. To
get a list of kernel packages installed on your system, run `dpkg -l |
grep linux-image`.

Write down the bug numbers of the bug reports on these links:
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bugs?field.tag=945g%20freeze&field.tags_combinator=ALL
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bugs?field.tag=945gm%20freeze&field.tags_combinator=ALL
(bug reports are removed from this list as bugs get closed). Check on
them in April and see if the have beeen fixed. At least some of them
will be the same problem that you have.

To check which kernel version introduces the freezes, there are
prebuilt mainline kernels at [1], see [2] for more info. We may be
lucky that the commit that introduced freezes on either 845G or 855GM
is the same one that introduces them for you. To test that, install
the kernels with freezetest8 and freezetest9 in the filename from [3],
if freezetest8 does not freeze but freezetest9 does, the problematic
kernel change is the same as for 845G. If not, install the one with
599 and 600 in the filename from [4]. If 599 does not freeze bug 600
freezes, it's the same commit as for 855GM.

The Karmic kernel 2.6.31-14-generic corresponds to mainline kernel
2.6.31.4. See [5] for a full list.
