Try adding this to your Section "Screen" after the last entry and before the EndSection

SubSection "Display"
                Depth   24
                Virtual 1680    1050
                Modes           "1680x1050"
        EndSubSection

It worked for me on my LG 22" lcd wide screen monitor using gutsy 64 bit and kde4.1.
