Until somebody decides to fix the Intel fb driver ;-) you have to patch the VGA
BIOS
( Read http://dev.gentoo.org/~spock/projects/uvesafb/faq.php )
e.g .for 1280x800:
* wget
'https://launchpad.net/ubuntu/hardy/+source/915resolution/0.5.3-1ubuntu1/+files/915resolution_0.5.3.orig.tar.gz'
* tar xvzf 915resolution_0.5.3.orig.tar.gz && cd
915resolution-0.5.3/ && make
* sudo cp -a 915resolution /sbin/
* read README.txt
* sudo 915resolution -l gives me
Intel chipset detected. However, 915resolution was unable to determine the
chipset type.
* for my chipset fgrep Chipset /var/log/Xorg.0.log
(II) intel: Driver for Intel Integrated Graphics Chipsets: i810, Mobile Intel
GM45 Express Chipset,
(II) intel(0): Integrated Graphics Chipset: Intel(R) 965GM
* forcing 915resolution -c G965 -l works

in the /etc/init.d/module-init-tools file just before the line
# Loop over every line in /etc/modules.
* be happy
