I own a Thinkpad T60p (Radeon M66 graphics) with a docking station, and I have discovered that the docking station has a slot for a new graphics card. So I was wondering: if I put a new graphics card into the docking station, would the laptop's LCD panel use this new card automatically when docked? Or would this card only be usable if I attached an external monitor to it?

Does anyone out there own any of these devices, and have you tried this already please?
