I saw in a previous post that you need to add a second Monitor
section, so you'd have two, one for the laptop display and one
for the external monitor.  It'd look something like:

Section "Monitor"
       Identifier      "Laptop Display"
       HorizSync       60-70
       VertRefresh     50-90
       Option          "DPMS"

Section "Monitor"
       Identifier      "External Monitor"
       HorizSync       60-70
       VertRefresh     50-90
       Option          "DPMS"

Use the correct sync and refresh rates though.  

I don't know how it switches.  Perhaps the Indentifier is more
that a label.  Hopefully someone else on this list can shed some
light on that aspect.
