Actually if you can get at least win95 on that laptop (easy) -- or windowsCE, you can run an RDP client and attach to a windows XP machine. You won't be able to play video at all, but GPS and stuff like that should work great. MP3 playing and whatnot might be a little tricky as it'd be hard to get the sound devices right, but that is still doable.
I can make you see bright stars and then blackness for a while with that device, but again, full motion video is going to be a problem.. it may be a little bit blurry.
