So if I understand correctly since https://bugs.debian.org/748398 radeonfb is now a module. What this means is that now instead of radeonfb taking the lead over OFfb, currently OFfb setup /dev/fb0 first (build-in driver takes over modules??). It is then impossible to load radeonfb since it lack something like:
