I meant to do that myself and forgot.  Thanks.

The above is the most important entry in the log file.  You have
an unsupported chipset.  Therefore, the nv driver cannot be used
unless you know the chipset to be compatible with another chipset
which is supported and you do a chipset override.  For example,
something like

   Chipset "G80"

in the "Device" section might work.  I'm not making any promises.
If it doesn't, look in /var/log/Xorg.0.log for error messages.
Sometimes, if you give an invalid value for Chipset it will list
what the valid values are, and you may find something there that
is close enough to work.

Another possibility
is to install the xserver-xorg-video-nv package from unstable, which
is newer and *might* support your chipset.  Otherwise, you're stuck with
the VESA driver, which uses the video BIOS to set video modes; and the
resolution you want, which is 1680x1050 I presume, is not one of the
video modes available from the video BIOS.  1280x1024 is the best that
the video BIOS can do.  Since your monitor *does* support DDC2/EDID,
you *don't* want to use 

   Option "NoDDC"

which is present in the "Device" section that you generated.  Take that out.
