I think if it's not going to be fixed on time for 9.10 release (and it looks that way) then probably a series of ATI r200 cards should get blacklisted for 3d effects. Ideally they should be blacklisted only for resolutions about 1024x768 if possible, since it seems that 1024x768 is the maximum working resolution.

Note that even at 1024x768 or less there might still be freezes in 3d that did not occur with 9.04, nobody tested this properly at this point.

I think a blacklist is needed and also maybe a mention in the release notes. A black desktop gives a very bad first impression of ubuntu and this is a clear regression from 9.04.

About my freezes, they occur with KMS at AGP8x (default), 4x and 2x. I stopped at that point and also because of https://bugs.launchpad.net/bugs/454847 decided to give up on 3d support on my graphics card for 9.10 (maybe I'll return to 9.04 I'll see).
