I'm seeing a similar hang sometimes when coming out of S3 as well. This just happened a few minutes ago. The compiz stacktrace this time was identical to the one above. I'm attaching .xsession-errors, which I note has a lot of "failed to get previous touch value" warnings along with some others. Xorg.0.log also had a number of "unable to find touch point 1" messages.
