When I switch to the Intel 4 series graphics the problem I'm experiencing goes away completely. I'm not sure how to describe the problem with the ATI card selected, but it seems an awful lot like LCD pixel walking that's only locally focused to bright patterns. It only happens on light colored gradients (especially white.) Another thing that seems to be part of this is white on black text kind of "vibrates" due to the diagonal lines moving across the display. Looking at the screen head-on, I can't see the waves, looking at it from at vertical angle (below the monitor) it's very much noticeable. Is this a driver issue with the ATI card, or do I perhaps have a faulty machine? Again, there is no problem while switched to the Intel card.

I've encountered the 'ripple' problem on desktop LCD displayers. It happens when your displayer clock is not optimised, which can be fixed usually by pressing the 'Autofocus' button on the LCD displayer.
I think it may be the same reason for your laptop. But surely there's no 'autofocus' button in Thinkpad. : P
