.X File export???

I am creating a game (Not with gameblender). But I only know how to use .X Files in my game (already modeled my objects in blender). Can i convert my blender files into.X Files?? Any help would be appriciated. If not… is there a free modeling program that supports .X exports?

check out http://www.cs.umn.edu/~mein/blender/converters.html

I believe someone else has made a .X exporter.
