(Get the code!)
@Rolf, note that loading the glx module explicitly doesn't do anything for recent X.org versions (it's autoloaded and so is "dri" module). Further, the permissions on the dri device node are also no longer in use because that device now has an ACL on it (so the "Mode 0666" stuff is obsolete). If you do "ls -l /dev/dri/card0" you will notice that the permissions have a small "+" char next to it, that indicates the presence of an ACL. You can see the ACL using the command "getfacl /dev/dri/card0".
Nice job with finding that patch btw. We usually never commit patches into Ubuntu before they are accepted by upstream though, so it would be useful if you first made sure that the upstream git versions has the bug fixed, then we can cherry pick patches for Ubuntu.
