Hi Jamie, excellent analysis work.  I can share some additional
background and analysis we've done on this class of bug.

A lot of people have found that the 2.6 driver series simply does not
work properly for them, and opt to either upgrade to 2.7 or downgrade to
2.4.  We have PPAs providing packages for each of these options, in the
x-updates and x-retro PPAs here:

If you want to focus on identifying the root cause of the issue, I've
written up some additional troubleshooting tips at
https://wiki.ubuntu.com/X/Troubleshooting/Freeze which may be of some
use.

I also put together some tools that help in diagnosis x freeze errors:

Unfortunately, we had found in the run-up to the Jaunty release that
most of the patches we tried that fixed a problem for one group, would
cause some unpredictable breakages for other folks with different
hardware; thus we're being extraordinarily conservative of introducing
patches for Jaunty's -intel, and focusing efforts towards getting the
issues resolved in the newer versions of the code, so Karmic is a solid
upgrade for everyone.

On that note, I would also encourage you to give a try of reproducing
the issue on Karmic.  Running a LiveCD of alpha-2 or a daily might be
worth trying, although I know with these freeze bugs often it can take
many hours or several days to reproduce the issue and running a livecd
may be impractical.

The good news though is that so far we're seeing huge improvements in
the Karmic -intel driver.  A ton of the most pervasive bugs have
vanished, and while there are still of course some problems, they seem
more of the corner case variety and seem to be getting good attention
when reported upstream.

If you do want to help chase down a patch for Jaunty for this issue,
I'll be happy to review and package it for Karmic and arrange to get
sufficient testing that we can prove it to be safe.  On the other hand,
if you're satisfied with one of the other options listed above, we can
consider that the fix.
