Hmm :-) Until 3 days ago I used intrepid on my Vaio FW21E, with the radeon driver, and it did not feel sluggish at all.
Although I could not enable KDE's desktop effects, overall drawing performance seemed very good.
In jaunty, X uses more CPU and painting is much slower, in comparison. I stopped using the fglrx driver a while ago since it causes too many wakeups, and KDE 2D drawing performance was awful.
