Erm - I didn't say that actually ;)   Heheh.  Anyway, I agree with Antony - 
leaving this i810switch in the startup will probably complicate matters.  
Leave it out for the time being.  Let's just focus our efforts on getting you 
a spanning (Xinerama) desktop.

Cool - let's get all that sorted for you.  However, one step at a time.  First 
the spanning desktop, then we'll worry about the cloning.

Yes.  We now know that you setup will support a second monitor and the 
hardware is all good (monitors, cables, interfaces etc).  So we need to set 
up the xorg.conf file so that it supports two monitors and a spanning desktop 
for you.

How did you go adapting those other config files I sent you the links for?

Always a pleasure!
