Uhh, will pospone this for now, will try to repair JFFS2 which doesn't 
work after the last month's commits. Crud! Not sure whom to blame so far.

Well, did not plan it. But we probably may add this functionality. We 
may borrow it from mtd2blk ...

Yeah, good feature. But I'm not sure how to implement an interface for
