As far as I can tell the only drivers involved would be output drivers,
ie. video output and serial output. There the extensible LinuxBIOS table
could come into play. The video driver could store a pointer to the
framebuffer, the resolution and maybe even a font, to save duplicates.
Serial is only a kilobyte or so of a driver i think.
Have I forgotten something?
