Hm, forcing people to use the DRM driver with fbdev emulation is
probably fine for most use cases. Currently you cannot use the fbdev
ioctrl to change modes/settings to the framebuffer which is probably the
only restriction...

It seems to me a rather extreme measure though, given we could fix the
situation rather easily.

But I am ok to remove the fbdev driver, if that is what we want.
