I have put modprobe fbcon after the first function to be called, 'init_system'. This calls it even earlier for even more rolling text at boot up. I have not got the balls to try it before 'init_system' as if I ballsax my system I could not face re-flashing this beast again.
mount -t proc none /proc mount -t sysfs none /sys mount -t tmpfs none -o size=512K /tmp mkdir /tmp/dev
Another interesting effect is the display of the green R&D mode text. If you look in the link you can call the display text without actually starting R&D mode. KInda cool if you want it but not rolling fbcon text.
