Increasing screen resolution

[andy <geek_show@dsl.pipex.com>]

Hi

I have started a new thread on this to avoid hijacking a similar thread 
from someone else.

My current screen resolution is 1400x1050 with a refresh rate of 50Hz.

This is my xorg.conf file:

I'd like to increase the resolution up to 1600x1200 with a higher 
refresh rate as well if possible. My monitor can take it, but my 
xorg.conf file no longer seems to have the section wherein one can tweak 
those settings.

I am using an Nvidia GeForce 8500GT card on a Lenny machine.

How would I go about increasing the resolution?

Thanks

Andy
