Valid xorg.conf file for linux OBI for DELL 630 Laptops

Seems like the next piece of text may be rather important if you are running the linux OBI on your laptop.
Everybody knows Marc De Weerdt ...(hope his name is in the correct tense) who provided the piece of plain ascii characters to be posted on this Hawtoes blog. Caught him correcting the file for one of our most junior people who came only just out his egg and started working with Linux. At least ... it's an intelligent chicken.
After you used it, be so kind to sent him all the honors. As well as ...any complaints and questions ...
