Nick, thanks for collecting a backtrace, however it looks like you did not install the debug symbols (the -dbg or -dbgsym packages), as you can see in the following where there are ?? instead of the functions. Please install them and collect another backtrace. Also, please do it by '(gdb) backtrace full' which collects more data than the default backtrace. I'll up the priority on this bug, thanks for filing it separate from 108527 which has gotten too crowded with unrelated issues.
For everyone else, I want to focus this bug on Nick's issue, which is with lockups with the ATI 9600. Unless you have the same card and exact symptoms, or unless you have *exactly* the same backtrace as him, please file a separate bug with backtrace and Xorg.0.log. Even if these turn out to be the same underlying issue it will make investigation easier to have them organized this way. We can always dupe them in LP if they end up being the same issue.
