I use the following in /etc/X11/xorg.conf. As my monitors are not exactly the 
same size, note that you'd probably need to edit the "PreferredMode" Option.  
I included those modes explicitly as one of my monitors was defaulting to a 
crappier resolution that what it could handle.

This works for me in F10 and F11 with the open source nouveau driver.
