Sorry - one more thing. Based on this thread: http://ubuntuforums.org/showthread.php?t=1985982
I did try booting a 6.6 kernel with "nomodeset", which did work. The behavior of the video was exactly the same as booting the "Basic Video" option of the CentOS 6.6 LiveCD - graphics were extremely slow and had a lot of artifacts/errors, but at least it did boot. I keep the Xorg.log file from this boot too. _______________________________________________ xorg-driver-ati mailing list [email protected] http://lists.x.org/mailman/listinfo/xorg-driver-ati
