Sadly, I haven't been able to get it to work. As per the logs,
everything goes OK:

(**) Option "Xinerama" "on"
(**) Xinerama: enabled
...
(==) RandR enabled
...
(II) Initializing built-in extension XINERAMA
...
(II) Initializing built-in extension RANDR

But xdpyinfo does not show RANDR, and xrandr fails with:

Xlib:  extension "RANDR" missing on display ":0.0".

I seem to remember that when I wasn't using Xinerama, RANDR was enabled.
Maybe RANDR and Xinerama cannot coexist?
