Actually, there is one really excellent side-effect of kernel
mode setting: The ability to manually override the EDID info
with a kernel boot parameter (figuring out how to use it might
be a different problem :-). This will finally be a single point
where you can lock down a monitor's video setting so the system
will boot right even when the monitor isn't currently connected
via the KVM switch or the monitor itself reports bogus EDID
