Your best bet is probably going to be to use a tiny UI that's designed for low resolutions. I have one that is designed for 1024x768, but has been used as low as 800x600 for boxing:

Stoplaughin's mini UI has some very nice touches too, with some really good looking tiny pieces (I love his spell bar).
