Maybe it just picks a video mode your panel(?) doesn't like.

Well, look at the xorg logfile.

There's a #define at the beginning of radeonfb.c which sets a default
video mode which is going to be used when there's no information about
the display available - should be "1024x768@60". The mode must be one
defined in src/sys/dev/videomodes/videomodes.c - maybe try a few others
that more closely match whatever your display likes.
