Problem with dualscreen after update to ubuntu 10.04

Hi fellow Linux users.

I have a thinkpad t61p with a 1920x1200 screen.
I also have at docking station with a 1920x1200 primary screen and a 1600x1200 secondary screen.
I use the recommend proprietary Nvidia driver for the Nvidia Quadro FX 570M graphic cart.

All worked perfect with my current xorg.conf file, until i updated to ubuntu 10.04.

The problem is that if I start up my computer outside my docking station it starts up with a 1600x1200 resolution, where it should be 1920x1200.
When i start up in the docking station all works perfect.

My xorg.file looks like this.
