Quirks mentioned before in this thread work with older xserver-xorg-video-package. Newest version which works on my Acer Aspire 5100 with "radeon_off" quirk turned "on" is xserver-xorg-video-ati_6.12.99+git20090825.fc74e119-0ubuntu2_amd64. You can download working package from: http://launchpadlibrarian.net/32142021/xserver-xorg-video-ati_6.12.99%2Bgit20090825.fc74e119-0ubuntu2_amd64.deb (for amd64) http://launchpadlibrarian.net/32141989/xserver-xorg-video-ati_6.12.99%2Bgit20090825.fc74e119-0ubuntu2_i386.deb (for i386) and install it with "dpkg -i" command. If you try this workaround please report if it works for you or not.
If it works for everyone then probably we should look what changes were introduced in next version: 1:6.12.99+git20090825.fc74e119-0ubuntu3.
