OF can stay blank sometimes, not initializing the screen, though I've 
only seen it
when autobooting, not when going into OF via cmd-opt-O-F...  mac 
doesn't turn on
the screen in OF until in the 'quit' routine (it provides the 0> prompt 
loop),
and if autobooting it doesn't turn it on all, it gets turned on later.  
I guess apple doesn't think OF banner is pretty, so they hide it, by 
keeping the display off.

But this isnt a autobooting... If you type "bye" does it reboot? or 
"shut-down"?
Is nvramrc set ?  Bad code there maybe?

(Note to self: see when and if nvramrc is eval'ed rel. to quit. )
