The good news: The new video card [1] arrived.
The bad: it's the wrong XXXXXXX card! I ordered a Dell nVidia GeForce 7300 LE. I received an ATI Technologies Inc RV370. Grrrrr.
The ugly: it does work, but it doesn't work at the resolution I require (or I don't have the proper drivers).
Back it goes, and we enter round two.
