Ok, short story is it's fixed.
I downloaded Amoeba, a demo app that uses OpenGL as a screensaver, and it forced my res to 800x600. It worked fine, but that res is too big. I switched my res back to 1280x1024, and Oolite started fine. So it works now.
Why I am not exactly sure.
Crashes at startup after setting change

Weird, it probably changed the system in such a way that the resolution Oolite wanted to use wasn't flagged as available, and Oolite crashed instead of trying to switch through all available resolutions.
Or something...
