--- Comment #7 from jonathan jonathan.voss@gmail.com 2012-03-06 19:41:29 PST --- This is a bit above my head I think. I got the source for xserver-xorg-video-ati from the Ubuntu repositories and tried to apply the patch to it. It looks like a lot of the right files are there, but there's no radeon_gem.c. The package version is 6.14.99~git20111219.aacbd629-0ubuntu2, which includes a date that I think indicates that it's not TOO old, however I cloned the git repository at git://anongit.freedesktop.org/xorg/driver/xf86-video-ati and had the same problem. I've also never tested a kernel mod so I'm not sure what I would do if I got the patch to compile.
