I believe that the option is permanently gone.  From the 302.07  
release notes (which was when the option was removed)

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

I am wondering if this setting was actually masking a problem with my  
set up in that it could be ignoring the EDID data and just sending  
whatever it had to the TV to sort out.  My frontend is connected to my  
receiver, not my TV and I have seen X report that it has no EDID data,  
but I need to look at that some more.
