The 64 bit kernels that apw provided fixed the described issue for me. Thank you.
To test, I created a kvm image based on the Precise daily from Jan 17. I ran the script that triggered the problem initially and verified that the problem still happened (the visual effect being a corrupted screen). I then installed the provided 64 bit headers and image using dpkg, and restarted the kvm. Repeating the script, the problem did not occur.
