Good catch, but shouldn't it work even without DRI?

Yes.

The module is already loaded. I can unload it though, even with a running X11 
session, "lsmod" shows that its refcount is zero. When loading it, it outputs 
"[drm] radeon kernel modesetting enabled." in dmesg. However, when starting 
the X server, it outputs "radeonfb 0000:00:10.0: Invalid ROM contents" there.

Note that this error is nothing new. X11 has been complaining about a missing 
ROM since I got this machine (MacMini), but has always worked nonetheless. If 
I understand correctly, the graphics adapter doesn't have a ROM and doesn't 
need one, because it is initialized by the firmware.

Thanks for your effort!
