Comment 22 for bug 289216

Another data point - this flicker issue is happening for me (running an updated 9.04) on a Thinkpad T60p with an ATI FireGL V5250 graphics card when it's connected to a 1680x1050 Dell 2209WA external display. There seem to be vertical regions that run the height of the screen, about 10-20 pixels across where, if the cursor is present, flickering is triggered. There are about 5 of vertical strips, roughly equally spaced on the 1400x1050 laptop display.

lspci output and Xorg.0.log attached.
