Default Re: Wrong 130Hz refresh rate in 800x600 and lower resolutions

That did the trick! Thank you very much.

In fact, it's enough to have:

Option "ModeValidation" "NoXServerModes"

After this xrandr shows:

   1280x1024      60.0*    75.0  
   1280x960       60.0  
   1152x864       75.0  
   1024x768       75.0     70.0     60.0  
   800x600        75.0     72.0     60.0     56.0  
   640x480        75.0     73.0     60.0
Exactly what I need.
So it seems like the nvidia driver incorrectly validates the list of pre-defined X-Server modes? Since my monitor tells it cannot do more than 75Hz, and I also tried to explicitly limit the vertical refresh frequencies range with the "VertRefresh" option, and it did not helped.

Let's hope the developers will fix this in later releases.
