Keeping 640X480 screen size at startup on Macintosh

I have a mac mini that is running a kiosk with a small screen. I want the screen to stay at 640X480, but each time it starts up , it resets back to 600X800.  It wont' seem to keep my display preferences.  

Is this something I can set up with Applescript? Or is there another answer. I am not good at writing applescript.

Thanks for the suggestion. I tried that, and switchresx requires Application Enhance, which doesn't work in Leopard
It  does now. The new one just came out. V 2.03 I am running it on my MBP intel c2d  running Leopard.
