Rig up a biger screen?

I have a 366mhz ibook with a 12inch screen. I can only get the resolution up to 800x600. it doesnt have a monitor out on it or anything. It really annoying to work with. Does any one know of a way to help me with this. is there a way top rig another monitor up? is there a way to upgrade it?

If you have OS X in it you could setup X11 server, get an old Pentium I PC (if you can find one), install Linux on that and use it as dumb terminal.
I don't think you would be able to use any native OS X programs, only Unix programs.

This would require quite a lot knowledge of *NIX systems and anyway I don't think it would be worth it. Sorry
