Either someone needs it so (not necessarily the same) someone fixes it,
or we remove it.

Note that this whole fbdev is deprecated in favor of (simple)drm. I
wonder if we want to invest any time to fix this mess at all? Or we
simply drop the defunct parts now.

I believe SUSE and Fedora (and others very likely too) are currently in
the process of moving away from fbdev completely at last. I don't know
the current state, though. Thomas?
