Your symptoms exactly describe a wedged GPU. There is a very good chance
that a 2.6.31 kernel would fix your issue.

It looks here that your entire stack is pretty old.  I would highly
recommend that you upgrade your stack; people generally don't enjoy
debugging problems that have already (possibly) been solved.  I've
experienced no graphics instability whatsoever on my GM965 Karmic box[1]
in the last few months.
