Set up each display subsection with the resolutions you want, similar to:

	SubSection "Display"
		Depth       24
		Modes       "1152x864" "1024x768" "800x600"
	EndSubsection

CTRL-ALT-+/- will rotate thru the modes you have defined.  Be aware, XFree86 uses a virtual
display, which if not explicitly defined, will be the first mode defined (i.e., the 1152
from mine.)  Moving the mouse to the edge of the screen will scroll the actual display around
the desktop. I know this sounds strange, but You'll See.
