The problem is in the kernel somewhere between 2.6.30 and 2.6.31-rc3. I can reproduce the freeze with both Karmic's Xorg driver (based on 2.9.0) and Jaunty's (2.6.3) with 2.6.31-rc3 and the system won't freeze with either Xorg driver on 2.6.30.
I'm using the mainline kernel builds at http://kernel.ubuntu.com/~kernel-ppa/mainline/ and at this point I have to start building myself because it's missing i386 builds for -rc1 and -rc2. But I've got a bisect building now on my laptop.
