Thanks for the tip Bob, close, but here is what I did. Your tip
definitely told me that I should dig into the manual for the nvidia
driver and see some options. I could not use the above because I do an
independent split of my X for my Myth to run on my TV. So some poking in
the nvidia manual I found "Option "ExactModeTimingsDVI" "boolean"" that
forces the initialization of the xserver to use the exact timings
specified in the mode line, instead of the closest mode it gets from
EDID. I also used the option "Option "ConnectedMonitor" "DFP" (and "TV"
respectively), versus the "UseDisplayDevice" option as the former
overrides what the xserver detects for the display devices. So, here is
an excerpt of my xorg file;

Section "Device"
        Identifier      "NVIDIA0"
        Driver          "nvidia"
        Screen          0
        BusID           "PCI:1:0:0"
        Option          "ConnectedMonitor" "DFP"
        Option          "ExactModeTimingsDVI" "true"
EndSection

Section "Device"
        Identifier      "NVIDIA1"
        Driver          "nvidia"
        Screen          1
        BusID           "PCI:1:0:0"
        Option          "ConnectedMonitor" "TV"
EndSection

And Voila! My monitor is now doing 1680x1050 display using DVI on my AGP
GeForce4 Card!
It would seem this was only necessary because of AGP, As I have done
multiple installs of high resolutions on flat panels using PCIE cards
with no tweaking of X.
Thanks again for the reminder to RTFM!
