Seems it has some problems with the OpenBIOS implementation of screen 
hansling so it could not draw to screen but it worked. Maybe you could set 
output to serial to avoid this but don't remember what are the options for 
that in OpenFirmware. You could try to add -prom-env "auto-boot?=false" 
-serial stdio to get to the OpebBIOS prompt instead of booting then enter

" scca" io

there to redirect input/output to serial then in the console window type 
boot to start booting so maybe yaboot would output to serial. Or there may 
be a better way setting input-device and output-device prom-env vars but I 
don't know what would be the correct value for serial output.
