Need to connect external monitor at startup for display to work

Greetings all. I've a rather peculiar problem with my iATKOS 10.5.2 installation on a Dell Insprion 1525. This is a laptop with Intel X3100 integrated graphics.

 

In order to use the system at native resolution (1280x800) I must first connect an external monitor to the VGA port and manually alternate to it using Fn+F8 at the bootloader. It will run through the boot process and display all the verbose messages on the external monitor if I have selected "-v". However it will automatically switch back to the laptop screen when the GUI starts up, and the VGA monitor will switch off. Doing this will allow me to access the Mac installation.

 

This was after applying the 10.5.2 Kalyway upgrade and the Apple Graphics Upgrade, to get my graphics card to work. Before applying both of those, I had to use the "-x" to get into a safe mode system, as it wouldn't boot in normal mode.

 

If I don't use that monitor trick, the startup process will go fine, but as soon as the GUI is ready to go the screen will go blank. It might flick the light blue screen up for a second but then it will disappear. Meanwhile if you move about the mouse or press some keys you will get disk activity so I assume the OS is actually fully operational in spite of the blank laptop monitor.

 

Any ideas? It's obviously a pretty minor issue but it's annoying to have to use an external monitor to start up the system.
