Nope, I think the patch in question was the clip solids patch to the
intel DDX driver. That patch does fix some GPU hangs, and for some it
meant that it would take longer for the computer to freeze. But the
cache coherency problem that is the big one right now is not affected
by this. So the clip-solids patch is included in Lucid LTS (and in
xserver-xorg-video-intel from version 2:2.9.1-3ubuntu2 on April 13)
but is unlikely to solve all freeze issues on 845G.

If you have a 845G and a stable Jaunty on it, I would stick with that.
