What options exactly?

Sure, radeonfb doesn't support the external output yet, so its behaviour is undefined with Option "UseFBDev". > I am on 2.4.20-benh10 / XFree86 4.3.

Absolutely, which is why the driver doesn't enable the external output when it doesn't detect a display connected (note that there may still be output coincidentally - have you guys checked in the log that the driver is even trying to drive the external output?)
