dual head on asus laptop

[Rich Healey <healey.rich@gmail.com>]

I'm using an Asus laptop (m6a) with intel drivers for X and works great 
at 1280 x 800.

I want to use a second display only when plugged in. I have a few 
questions ->
   1. does anyone know where i can poll the /dev tree to find out if 
there's a second monitor plugged in
   2. does anyone know another / better way to find out if there's 
another monitor plugged in
   3. does anyone know what the best way to configure the dual head is 
for this? using a second screen "newscreen" RightOf "oldscreen" in my 
xorg.conf didn't go well (entrance tryingt o fire up a dud X config 
every 30 seconds).

Cheers
