Well, I've made n800 to be additional screen for my HP Mini 2133 and since it has an insane resolution (1280x720 in 9") the DPI is pretty similar to nokias. BTW. I've made a mistake. You still need ZoneScreen cause XP resets secondary display settings after restart. So to fix it automaticaly you should run ZoneScreen, configure it as described and select "File - Save configuration to run as startup". That will make everything good.
