Apple cinema display 20" / 1680x1050

Hi
I am trying to config my apple cinema display on Fedora Core 3.  I tried to
config the xorg.conf file and add the below line to the monitor section:

ModeLine     "1600x1024" 108.0 1600 1616 1656 1704 1024 1027 1030 1056 -hsync
-vsync -csync


--------------------
Section "Monitor"
	Identifier   "Monitor0"
	VendorName   "Apple"
	ModelName    "Apple Cinema Display 20"
	HorizSync    31.5 - 67.0
	VertRefresh  50.0 - 75.0
	ModeLine     "1600x1024" 108.0 1600 1616 1656 1704 1024 1027 1030 1056 -hsync
-vsync -csync
	Option	    "DigitalVibrance" "50"
EndSection
---------------------

The screen horizontal seems to be bigger than my monitor so when I move my
mouse up and down / the screen moving also.  When I looking to the resolution
section, it show that my screen set up at 1600x1050.  My monitor suppose to be
at 1680x1050.

Thank for all your help.
