No, you can't print with a framebuffer console in graphics mode.
You ignore the accelerator, which may be operating when you want to
write to the screen. Some video cards will crash. GGI could write
to the screen because GGI knows what the accelerator is doing.

Like DOS, temporary hacks live on forever because nobody wants
to rock the boat. :-(
