Problem solved. Needed to add nomodeset to the boot parameters.

Here's a link to a thread with solution: http://ubuntuforums.org/showthread.php?t=1613132


I had this error while testing 12.10 alpha 3 and had to place 'xforcevesa' in the boot command line to get a screen, but once installed it seemed to clear itself.
