Comment 74 for bug 133192

Unfortunately this bug did not get sorted out for Gutsy-final. However, since -ati had a lot of new code and is still being stabilized, we anticipate doing at least one hotfix for the -ati driver for Gutsy. Because it will be a hotfix, though, we need to be absolutely certain there is no chance of regressions for other users, so it may take some time to ensure the fix solves this problem and causes absolutely no others.

I suspect that most people commenting on this thread are having unrelated issues. Unfortunately, due to the bug's generic title "Screen displays garbage", I think that's causing all sundry of -ati issues to collect here. It is possible that some of these disparate issues have the same or similar root causes, but in general unless you experience exactly the same symptoms as Wouter, then it's likely you are having a distinct bug that should be reported separately.
