Package: xserver-xorg-video-ati
Version: 1:6.6.3-2
Severity: important
Under Etch, iceweasel is fast on X server with EXA.
After upgrade to Lenny, running iceweasel makes the X display
unresponsive (1-2 second lag ). I'm often unable to drag windows
around the screen as the window just ignores the input. CPU usage
by Xorg maxes out.
I know this is a problem with the X server not iceweasel because I ran
etch under chroot and etch's iceweasel had the same laggy/CPU-hogging response.
Radeon 9250, 1920x1200x24bpp
xorg.conf attached.

This is a known problem with Xserver 1.3 and EXA on the ATI driver. EXA
is great for compositing (compiz, beryl, ...) but not always good for
other applications. You should switch to XAA.
