Putting the same information into different modeline generators produces 
different results. What's a feller to do?

Used 3 different sites to work out modelines for 1024x768 at 66, 70 75 
and 85Hz. Only the last one also let me enter Dot Clock Frequency.
Not at my Myth machine at the moment. Just getting a list of things to try.
