FC3 + Dell WUXGA Screen + NVidia = Working Configuration

[Gregory Gulik]

This is very interesting.

I've been struggling with my Toshiba laptop with a WXGA 1280x800 
display.  I've seen several xorg.conf files all have issues so I've been 
trying to figure out the format myself.

My specific question is how do you determine how to write your own 
ModeLine?  Do you have a reference to good documentation on how to make 
my own?
