It takes a few changes:

1. In /etc/default/eeepc-acpi-scripts, modify the COMBINED_DISPLAY_SWITCHES 
variable.

# these are the switches for xrandr --output VGA when Fn-F5 is used to
# select LCD+VGA mode
COMBINED_DISPLAY_SWITCHES='--output LVDS --below VGA'

2. In /etc/X11/xorg.conf, two screens have to be defined (with their 
corresponding display and device sections), with max virtual resolution. I 
have found that what works best for me is having the small eeepc display 
below my big screen. This makes the small eeepx screen a continuation of the 
large top screen and I can have windows display across both as in xinerama 
mode of the old X display drivers. This way I can simply [Fn][F5] to get 
everything on the eeepc screen or displayed across both.
