You may want to check /etc/X11/Xorg.0.log to see if any 1280x800 modes 
are recognized.  If not, you may need to use 855patch: 


I use 855patch on my Dell 700m to get 1280x800.   Then you need to add a 
ModeLine to xorg.conf. 

ModeLine "1280x800" 71.0 1280  1328  1360 1440 800  802  808 823

and make the appropriate changes in xorg.conf to use this as the default 
resolution (colordepth 24).  Use the i810 driver.
