I believe your using the wrong driver try the module intelfb if not present download latest linux sourcecode from kernel.org and get kernel-package, make, libncurses5-dev, zlib1g-dev, gcc from debian repository kernel-package comes with a documentation in /usr/share/doc/kernel-package or get a newer kernel from a repository
so what you you have to do is download from debian testing repository the latest kernel for now it's linux-image-2.6.26-1-686 and install it with
dpkg -i linux-image-2.6.26-1-686_2.6.26-12_i386.deb
or do the following
apt-get install kernel-package make libncurses5-dev zlib1g-dev gcc bzip2
wget -c http://www.weedlight.ch/help/config-2.6.26-1-686
wget -c http://kernel.org/pub/linux/kernel/v...2.6.28.tar.bz2
tar -xjf linux-2.6.28.tar.bz2
now you have to load the old debian config file 'config-2.6.26-1-686'
make-kpkg --initrd --revision=custom.1.0 kernel_image
dpkg -i linux-image-2.6.28_custom.1.0_i386.deb
I'm having a similar graphics card in my laptop and I had graphics support after installation but I compiled the kernel by my self as shown above to get my wifi card to work with iwlagn driver
If you have also a laptop perhaps you want use my kernel image http://www.weedlight.ch/help/linux-i...m.1.0_i386.deb
it's only for laptops!
