Is there some existing way to do early printk type output to a
framebuffer that has been set up by the bootloader?  early printk is
before any device drivers are loaded.
arch/m68k/kernel/head.S does this on Mac.

ISTR offb also used to do that on PPC, or perhaps it was the
old PowerMac console driver we had before that.
