Ok I just tried this. I booted up the laptop without the dock, 
and when I was in X using only the laptop internal display I connected 
the laptop to the docking station (which has external display via DVI).

Now I could go to Gnome Monitors application, see the external DVI display,
enable it and I got picture there!

.. just once. After I disabled the external display, and tried re-enabling it, 
it didn't work anymore.. no picture on the external display anymore.

Also something weird:

The external display is being shown twice.. for some reason?

I'll try Ubuntu 10.04.

I haven't tried custom/non-distro kernels.
