As Mario said, xserver-xorg-video-ati 6.14.3 completes the fix for this bug. From the changelog:
radeon: add support for llano APUs radeon: add llano pci ids
This first appeared as a backport in Oneiric in xserver-xorg-video-ati 1:6.14.2-1ubuntu2 and was then mainstreamed in later Oneiric packages.
I have also verified that Ubuntu 12.04 "Precise Pangolin" boots and functions normally on a laptop with an E-350 and Radeon HD 6310 graphics.
