If there is some surefire way to tell which monitor is connected, then
it should be a simple matter to restart X with a script that checks
which monitor you're using and points to the appropriate xorg.conf
(or even changes the file directly (not recommened)). 

If monitor detection is not really possible (I personally wouldn't
know how to do it) then a simple script could be used to change a
symlink to point to the appropriate xorg.conf. then an /etc/init.d/*dm
restart would fix you right up. 

there are many solutions but essentially you have to set up some
situation where you can put different xorg.conf's in place as needed.
