I think we can improve on top of this and leave keyboard.c out
completely in the future if no keyboards are enabled.
I'd be quite happy to have input support, but that depends on currently
pretty much non-existing OHCI support.
Later I will probably add serial console support back to my images, but
that depends on getting the serial port GPIO mux with VGA DDC turned
back to DDC mode post-bootloader on a GeodeLX that I need to figure out
how to do cleanly.
