Binary package hint: xserver-xorg-video-ati

There's a serious desktop effects performance regression in Kubuntu
Natty. KWin reports < 20 FPS what makes desktop effects unusable. In
Kubuntu Maverick, KWin reports 60 FPS.

A similar performance regression can be observed after updating i386
Maverick with the latest Xorg server and drivers from xedgers-ppa.
