	Modelines really shouldnt be required unless you have certain
requirements in regard to the timings. A modern Xorg server will 
have a billion built-in modes, and it will make all of them available
that are within the constraints of your monitors specs and the available
clock settings of your video card.
	So, usually under the Screen section, you specify the resolutions
you personall want under the Modes. Then, these will be available for
you to easily cycle between via ctrl-alt-<plus> and ctrl-alt-<minus>
(+/- on the num-pad). Xorg will have chosen the best refresh for the
resolutions that does not endanger your monitor.
	Now, in this case, the virtual size of the desktop will still
be the size of the largest Mode. You may have to leave out a higher
res if this is a problem, or just run another X server on another
	The 'xrandr' command can also list all available resolutions
and refresh rates and allow you to force one.
