Whoa, a D270 with an N2800? You lucky dog! 
Have you tried manually installing the driver, i.e. go into Device Manager, right-click on the GMA 3600 item, click "Update Driver Software...", "Browse my Computer for Driver Software", "Let me pick from a list...", click Have Disk, go find the folder driver, etc? You'll need a folder with all of the driver data in it for that last step. If you can't find the place where Intel's installer normally dumps its files, you can download a zipped-up driver from
Hope that helps!
