I am using HP dv1040us notebook. It is a centrino with onboard intel 855
chipset. I am running mandrake 10.1 and kernel 2.6.8.1-12mdk, xorg
6.7.0-3mdk.

I cannot get the display to work with more than 1024x768. The X log shows
that the panel size is discovered to be 1280x768 but when I try that mode
in the XF86config file, the screen is garbled.
