I will look at the new kernel fix and verify with xset dpms. I did notice an update of xorg-intel driver in the respositories yesterday (May 4). Since a lot of the earlier posts were related to compiz, I just want to note here that I also ran into the same problem on Kubuntu (no compiz) as many users above, after upgrading to Natty official release. I am using the intel i915 driver, and the official 2.6.38-8-generic kernel revision.

The GUI freeze (although the mouse works) seemed to happen randomly: once when browsing with chrome, once with firefox, and once editing a text file with kate. In some cases, I was able to switch to a terminal and run dmesg. I unfortunately didn't dump the output to a file (I will next time), but the last lines were errors related to DRM and the intel GPU. It indicated a GPU freeze. I will paste the dmesg output here on next freeze (my apologies).
