Hi, I had problems with mine initially on both DVI and VGA, I have a
geforce card and it wasn't untill I updated the nvidia driver I
finally got the right mode to work.
I know nothing about ATI cards/drivers but here is my XF86config-4

Option "AGPMode" "8"
Option "DigitalVibrance" "0"
Option "NoLogo" "1"
Option "HorizSync" "DFP-0:30-81"
Option "VertRefresh" "DFP-0:56-76"
EndSection
Section "Monitor"

Modeline "DELL1920" 193.16 1920 2048 2256 2592 1200
1201 1204 1242 -HSync +Vsync
EndSection
Section "Screen"
Identifier "Screen1"
Device "Generic Video Card"

Also try this site to generate a mode http://xtiming.sf.net/
or use the tool "gtf" that comes with X
I hope you get it working!
