The it won't work. I had huge problems until I realised that the 
modelines had to exactly match the modes - in your case, you need at 
least one modeline that is called either "1920x1080_60i" or 
"1280x720_60" in the monitor section. Call them whatever you like, but 
the strings have to match. I use an FX5200 and this works great for me. 
I have no implicit modeline in my nvidia driver (latest version).

This works for my Panasonic PTA700E:

Section "Monitor"
    Identifier "Monitor0"
    VendorName "Panasonic"
    ModelName "PT-AE700E 1280x720"
    HorizSync 31.5-90
    VertRefresh 60
    ModeLine "1280x720"     76.45   1280 1340 1676 1700    720  735  
742  757 -hsync +vsync
EndSection

Section "Screen"
    Identifier "Screen0"
    Device "Device0"
    Monitor "Monitor0"
    DefaultDepth 24
   
    Subsection "Display"
        Depth 24
        Modes "nvidia-auto-select" "1600x1200" "1280x1024" "1280x720" 
"1024x768" "800x600" "768x576" "640x480"
        Virtual 1280 720
    EndSubsection
EndSection




BTW - you didn't include your whole xorg.conf, so I'm assuming here :-)

HTH.


Cheers,
