just adding AGPSize 64 to my existing xorg.conf (taken from https://help.ubuntu.com/community/RadeonDriver) works for me, without kms and without downgrading libgl1-mesa-dri.
I'm now using Extra Visual Effects at the same speed it was on jaunty (or at least I can't notice differences in browsing, playing flash video, etc).
