At least we'd need a way for display drivers to access EDID data so the
iic stuff would need to be attached first. Maybe it makes more sense to
add some ioctl to wscons instead of using a separate device and then
going through the hassle of figuring out which /dev/iic/monitor* belongs
to which display.

have fun
