Like Darrin suggested try matching Modelines and Modes :
On xorg.conf
Enable only this (comment the rest of the modellines) :
Modeline "1680x1050_60.00" 147.14 1680 1784 1968 2256 1050 1051
1054 1087 -HSync +Vsync
Modify the screen section :
Section "Screen"
Identifier "Screen0"
Device "Card0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Depth 24
Modes "1680x1050_60.00"
EndSubSection
EndSection
