Just because you put a modeline in the xorg config, does not mean the 
videodriver, monitor or card itself, supports that mode.
Inspect /var/log/Xorg.0.log, specifically the supported modes detection,lines 
like:
(--) NVIDIA(0): Interlaced video modes are supported on this GPU
(--) NVIDIA(0): Connected display device(s) on GeForce Go 7600 at PCI:1:0:0:
(--) NVIDIA(0):     Seiko (DFP-0)
(--) NVIDIA(0): Seiko (DFP-0): 330.0 MHz maximum pixel clock
(--) NVIDIA(0): Seiko (DFP-0): Internal Dual Link LVDS
(II) NVIDIA(0): Assigned Display Device: DFP-0
(II) NVIDIA(0): Validated modes:
(II) NVIDIA(0):     "1440x900"
(II) NVIDIA(0):     "1024x768"
(II) NVIDIA(0):     "800x600"
(II) NVIDIA(0):     "640x480"

It's also helpful to know the make and model of your graphics card, and which 
driver you're using for it.

Problem with today's modular software: they start with the modules
    and never get to the software part.
