The losssage is such a deep root in which pmax rcons uses a global
array struct tty rcons_tty[NRASTERCONSOLE] instead of ttymalloc(). In
retropect, the attempt to have psuedo-device rasterconsole/fb has
never been successful, and graphics console should be replaced with
wscons in favour of consistent approach and implementation.
