As DVI has no knowledge about aspect ratio, this is certainly not true!
Again, this is about single link interfaces and their maximum pixel
clock of 135MHz. A non-reduced mode (that can be used for CRTs as well)
needs 147, so it is not working. A reduced mode only needs 119.

Also, 1680x1050 is *no* HD mode - only 1280x720 and 1920x1080 are. And
they are 16:9, not 16:10 as 1680x1050 is.

Add the reduced mode line and the options I've written, and it *should*
work with DVI - it did with a 5300. I just reviewed the bug, you might
need to add "NoMaxPClkCheck" as well. Mode validation has changed quite
a bit in the newer NVidia drivers.
