It depends on what version of X11 you have. I remember on prior versions I would need to use this hack in order to get 1280x800 on my laptop. Newer versions of X11 made it unnecessary, though.

This looks like what you have:

If this is the right one, then it has Intel GMA 900 graphics
Some snooping around suggests that the driver for this will already be in your distro. Look in /usr/lib/xorg/modules/drivers for something like this:
intel_drv.la*
intel_drv.so*

In the device section of /etc/X11/xorg.conf you would simply specify "intel" for the driver.

Once the right driver is setup, then you should be able to enter the desired modes in xorg.conf

my graphic card is mobile intel(R) 915GM/GMS,910GL Express Chipset;i try the hacks and get back to you
