I dug out a PS/2 keyboard which works.  When adding
modprobe.blacklist=radeon then GDM does not start.
/var/log/gdm/greeter.log contains beside various expected errors for
fbdev:

(EE) open /dev/fb0: Permission denied


So i did

chmod 777 /dev/fb0
herd restart xorg-server

but it still says permission denied on /dev/fb0.
