How can I run a cmd script when I "Undock"?

[JHaislet]

I'm needing to run a simple cmd line script when I undock the T43 from the Dock II.

I've installed Media Center 2005 and the actual Media Center program was tying up the TV tuner, thus not allowing it to undock.

So I wrote a simple script that kills the media center application and I'd like to be able to run that at the same time I click on "Undock" from the Start menu, or using the IBM Fn+F9 EasyEject Utility.

Any ideas?
