F/OSS Virtualization Software?

Question - Does anyone know of any Free Software virtualizors/emulators besides plex86 (which looks to be a special purpose one now) and bochs? Specifically, I'm looking for an emulator that will let me run Warcraft 2 (what can I say, I like the old games). It's either that or try and build/scrounge/ebay up an original Pentium and put FreeDOS on it.

Ideas?
