I think I saw somebody complaining in the nVidia forum that when 
switching video modes, overscan settings are lost.  But that you can put 
them back with the new nvidia-settings tool.

If that's the case, you could write your own 'xrandr' shell script that 
does the xrandr and then fixes overscan.  Just make sure it's first in 
your $PATH.  This will work unless & until you start using John Poet's 
multi-resolution patch, which calls the xrandr library directly rather 
than issuing a command.
