I don't remember being able to do restores from 6.5 to 7 or 2000. The file structure is ENTIRELY different, first big difference V4-6.5 used 2K pages, 7-Present use 8K pages.. And thats only the start.. I think you need to use the wizard and migrate the database from 6.5 to 2000 and then you should be able to attach or backup/restore it to any same or higher version..
