Just to update the the behaviour somewhat:

According to xrandr, the LVDS (LCD panel) screen is connected. I can use
xrandr to tell the LVDS screen what resolution to display, and can set
the display to off. When the display is set to off, the backlight goes
off, suggesting that the panel is simply not being sent the signal when
it is on.

However, LVDS still describes the panel incorrectly - it should be 1920x
1200, but I get the following from xrandr...

roger@ubuntu:~$ xrandr --prop

No display on LCD panel when the fglrx driver is installed. Display on external VGA still works.
