Good point Tom, it does seem strange that the log files say that the monitor
is capable of supporting the 1024x768 mode but then won't let us use it..
maybe there's some interplay between the monitor & X going on that it's not
telling us about...
Damian, yes the reason I said "_60" specifically is because the Nvidia
drivers seem to have this 60hz restriction, obviously we've tried to turn
that off but maybe it's not listening? So we go for 60hz as a first step...
