Unfortunately, I don't think you'll have much luck with any of the TW games under Linux. Some people have apparently gotten parts of it to work under Wine, but as of yet, nothing you'd probably want to try to play.

Sounds like you're stuck with XP for now. No reason not to dual boot though, if you want to play around with Linux. Recently, I've run Hitman2 and Warcraft3 under Wine flawlessly along with a growing list of native, free games.
