I am not sure about having two "Device" sections. I have an Intel 855GM
Display Controller in my laptop and I only need one Device section to
have the two outputs. Your card should use the same driver so I would
expect that it should work similarly.

I can post a working Cloning configuration and I am sure that
somebody else will have an example for a proper Xinerama setup, but
first we need to know that the "i810" driver works properly for you.

just hoping that someone posts these xorg.conf's for the record; I for
one may well buy one of these machiens soon and would like to know how
to do both things.

Here are the relevant parts of my xorg.conf for a cloned setup with an
Intel 855GM card:

EndSection

Section "ServerLayout"
Identifier "Cloned"
Screen "LCD Cloned"
InputDevice "Keyboard"
InputDevice "Touchpad"
InputDevice "USB Mouse"
EndSection

#-----------------------------------------------------------------------

This allows me to run

startx -- -layout Cloned

to start X with the cloned display, and

startx -- -layout Default

for the normal display (external output off). If you only want the
cloned display then you can remove the normal "Device", "Screen" and
"ServerLayout" sections, of course.

To avoid confusion due to my earlier statement about the two "Device"
sections in the OP's xorg.conf: Yes, I do have two such sections as
well, but in my case only one is used at any given time, depending on
the ServerLayout.

This xorg.conf works very well for me, but I actually prefer to use a
normal (not cloned) xorg.conf and to switch the external output on/off
with the i810switch tools. (I do not have to restart X for the change to
take effect in that case.)

I never had any reason to play around with Xinerama, therefore I do not
have a configuration ready for that case.
