It is always useful to reference the sources you are mentioning so people 
can interprete the information themselves.

On a Dell D610 at work, I am doing this:

	/usr/sbin/915resolution 38 1280 1024
	/usr/sbin/915resolution 3c 1400 1050

To make the external and internal video to work with the correct 
resolution. I assume what you need to do is something similar.

PS Are you sure it is 1440x900 ? Mine is 1440x1050...

PS2 The X configuration should work barebones. So no specific ModeLines 
are necessary. But what worked here as well was the following 
configuration file (for a Xinerama dual-head setup using the internal LCD 
and the external TFT).

A lot of stuff in there however was things I experimented with, so your 
mileage may vary.

Kind regards,
