With a daily live image of Kubuntu Karmic (11/7) the issue remains. I also tried booting up in single mode (still on the live image), and updated xserver-xorg-core, xserver-xorg-video-intel and mesa packages from xorg-edgers, to no improvement.
In preparation, while still in the cli I installed openssh-server and managed to stay connected with my other machine when it locked. From this ssh session I have *full* control of the system, but I still can't recover. dmesg didn't say anything interesting, but I saved a copy of Xorg.0.log and a gpu dump at this point, which I'll attach.
I tried stopping kdm, but it wouldn't respond to SIG_TERM (only SIG_KILL), the X process likewise. Trying to restart kdm - and by extension X - spawns both processes but just makes the screen modechange and stop again.
At this point I started getting dmesg output I hadn't before; this is when X is trying to restart. It didn't output this when it had just hung, if that is of relevance. (Might've already attached it before this comment, browser malfunction)

dmesg: http:// pastebin. ubuntu. com/215581
It's easy to reproduce the steps to get here, if you want me to produce output of other commands.
