Have you tried a config-file entry/snippet:
==
Section "ServerFlags"
        .
        .
  Option "DontZoom"  "off"
  # This disallows the use of the Ctrl+Alt+Keypad-Plus and 
  # Ctrl+Alt+Keypad-Minus sequences. These sequences allows you to
  # switch  between video modes.  [...]
        .
        .
EndSection
