Me too (with Nvidia, never had an ATI card). I had Thinkpad T510 with Nvidia and used it with two monitors plugged into docking station. Nvidia's proprietary driver is absolutely horrible when it comes to switching between laptop screen and monitors when docking/undocking. Open source driver for nvidia is marginally better in this regard, but is incomplete and unstable and not really an option. Now I have T520 with Intel graphics, and it works very well.
