It was the video card driver!

An admin friend mentioned that X can get confused probing video cards.

So even though Xorg -configure reported this:

         Driver      "ati"

which I was inclined to believe, since the card *is* made by ATI, when
I changed it to this:

         Driver      "vesa"

It worked!
