I haven't had to use old-style modelines in quite a while.  Try adding a
Monitor section with appropriate HorizSync and VertRefresh parameters (you should
be able to find them somewhere on the 'net:

 Section "Monitor"
    Identifier     "Monitor0"
    VendorName     "Samsung"
    ModelName      "Samsung SyncMaster"
    HorizSync       30.0 - 81.0
    VertRefresh     56.0 - 75.0
 EndSection
 
And then make sure your Screen section points to the Monitor:

 Section "Screen"
    Identifier          "Screen0"
    Device              "Your Device"
    Monitor             "Monitor0"
    DefaultDepth        24 

    SubSection "Display"
        Depth           24
        Modes           "1024x768" "800x600" "640x480"
    EndSubSection
 End Section

You may need other options and sections, depending on your setup, and
you'll need to specify the section for your graphics card (device) as
well.
