I strongly suspect that it would be much easier to figure out how to do
it from xorg.conf.  Have you read the static setup section of
http://www.intellinuxgraphics.org/dualhead.html ?

If you used gdm, you could edit /etc/gdm/PreSession/Default and add the
xrandr invocation there.  I've no idea what's the equivalent for kdm.

script and a program. She'd probably look at you funny, then say something
like: Well, a script is what you give the actors, but a program is what you
give the audience.
