Are you running version 1.3 of the X server? Do you have a RandR 1.2
capable version of xrandr?

Yes, a known regression. A preliminary patch for this has been created,
but it's not ready for integration yet.

The 1.3 version of the server with a RandR 1.2-capable version of xrandr
should make all of this 'just work'.

xrandr --output VGA --above LVDS --auto

should 'just work' and give you a desktop spanning both monitors, as
long as you have 'Virtual 2048 2048' in your xorg.conf file.

You don't want to use the Xinerama option with the 1.3 version of the
server. Yes, segfaulting is 'bad', and should be fixed.
