yes this is because i had to write all my text directly to the
framebuffer, apple takes all kinds of special efforts to prevent
`archaic peecee text' from showing up on the screen...  this problem
should be fixed in yaboot 2.0

i don't consider it too serious right now since if your doing serial
console your probably not running any macos.

you could probably fix this easily enough for your setup by altering
the `.printf' definition in ofboot.
