In the 3xx.xx series they removed FlatPanelProperties.  You can't use
this anymore and this is what is causing my issues (I believe).  For
some reason my Onkyo receiver does not give all the correct modes so I
need to specify them in my xorg.conf.  The problem is I can't figure
out how to make it work with FlatPanelProperties gone.  It appears you
need to specify every single possible metamode you may encounter.  I
finally decided 295.75 worked for me and I'd stick with it...

This is from the release notes of (I believe) 302.17:

- Removed Flat Panel Scaling configurability in nvidia-settings. Any
desired scaling can be configured through the new "ViewPortIn" and
"ViewPortOut" MetaMode attributes.

- Extended the MetaMode X configuration option syntax with the
following new attributes:

"Rotation" : specifies the display device's rotation
"Reflection" : specifies the display device's reflection
"Transform" : specifies a 3x3 transformation matrix to be applied to
the display device
"ViewPortOut" : specifies the region of the mode in which to display pixels
"ViewPortIn" : specifies the size of the region in the X screen to
display in the ViewPortOut

For example, "DFP-0: nvidia-auto-select { Rotation=left }".
See "Configuring Multiple Display Devices on One X Screen" in the
README for details.
