Well, vesafb assumes the VESA BIOS initialized the card to some linear graphics
mode _before_ the real kernel code was started. Once the kernel is started, no
VESA calls are made, and the video mode is fixed.
So in theory (and you proved the practical side on PReP) it can be used on any
platform that initializes a more-or-less VGA card to a linear graphics mode.

when I'm talking to journalists I just say "programmer" or something like that.
