You ignorance does not dictate reality.

[joking, really...]
Milkshape 3D has a .X mesh reader in the tools menu. Pricy conversion tools like Deep Exploration can read in .X in a snap.
Have you tried opening the .X in Notepad? The majority of .X files are in plain text format. Just do a word search for quotation marks and you will find the file names. Simply change the extentions from BMP to JPG, save the file, and you should be good to go.
