Well... I update every _daily_, and the issue persists.  I have a log of
xrandr when this happens... it happens when I try to switch from Laptop
to Dual monitor with the previous xrandr script.

What I do now to work around my issues...

When I dock, the display menu does not recognize my monitors... so, I
use the dual-monitor script to select the two monitors (which results in
"tiny" screen... then run a script that sets xrandr to turn off those
monitors and turn on LVDS.  Then... I use the display settings applet
again, and magically my monitors appear... then I use display manager to
set my docked monitors properly.  CLEARLY, this is "hokey" -- so... it
would be better if it were fixed.

Here again are the dual monitor script and the laptop script:

$ cat dual-monitor 
#! /bin/sh

# script to do multi-monitor on my T400 box
# fglrx script
xrandr --output LVDS --off && \
xrandr --fb 3200x1200 \
       --output DFP1 --auto \
       --output CRT1 --auto --right-of DFP1

$ cat laptop 
#! /bin/sh

xrandr --output CRT1 --off
xrandr --output LVDS --auto
xrandr --output DFP1 --off && xrandr --fb 1440x900
