HP Comaq 6720S problem with i965 graphic

I use HP Comaq 6720S, trying to install openSUSE 10.2 (Kernel 2.6.18.2-35). After installation resolution is 800x600, but i need 1280x800. Graphic chip is mobie intel965 express chipset family. “915resolution” tool(915resolution: Intel Video BIOS Hack) not helps, says that “graphic chip not identified”
How can i decide this problem?

Considering the fact that 1280x800 resolution
worked straight away after install in my system
(HP Compaq 2710p, 965GM, OpenSUSE 11.0, 2.6.25.16-0.1-default),
I suppose you need to update to newer kernel, or newer XOrg/915resolution packages.

Or maybe you are able to install OpenSUSE 11.0?
