dual-head or xinerama is the wrong solution for that purpose.

i810switch is one tool, but not working properly with the 945GM. You only can 
use it once then a restart of the xserver is necessary.

I just changed the device-section as follows:

Section "Device"
        Identifier      "Intel Corporation Mobile 945GM/GMS/940GML Express 
Integrated Graphics Controller"
        Driver          "i810"
        BusID           "PCI:0:2:0"
        Option          "AccelMethod"           "EXA"
        Option          "clone"                 "true"
        Option          "MonitorLayout"         "CRT,LFP"

This produces a clone on the external VGA and is working fine.
