I can also confirm this running Jaunty AMD64 with a Radeon XPress 1250.

I decided to play around with some of the drivers from X on the Edge, and in running the latest available:

xserver-xorg-video-ati
xserver-xorg-video-radeon
1:6.12.2.99+git20090504.da58e351-0ubuntu0tormod

I have yet to see any screen flickering with or without visual effects running the processor on the "powersave" daemon, even when trying things such as rapidly moving a window around the screen, and maximizing a terminal and running the command

cat /dev/urandom
