Adding a new resolution to drivers?

[AseStar]

Hello
This question is mainly for people who know how to edit regitry or ini files
of catalyst (or omega) driver.

I have a laptop with wxga screen. Native res is 1280x800. But it runs only
at 60Hz. Now I know for lcd refresh rate don't matter, but at 60Hz, my mouse
pointer is NOT smooth. So I want to add 1280x800 @85Hz in drivers (or
registry).

I tried "mobility mod tool", while it adds all other laptop res (like
1280xx768, or 1400x1050) at 75,85,100hz, it only adds 1280x800 at 60Hz

I have experience in editing catalyst and omega ini files before, so feel
free to comment.
Can anyone help me out?
