I guess no one liked that idea?

How about at least making sure that the real console gets a message that
something is on the bootconsole? Right now the switch message:

console handover:boot [early_shadow0]  -> real [ttyBF0]

only is printed on the bootconsole, not on the real console - so someone 
looking at the real console may not know there is anything on the boot 
console. They just think that things are missing...
