Ok. Well I don't really have any other ideas, it's just a typical mistake 
that people make (I do it all the time...).

What happens if you erase the flash and the mount it directly (without 
writing an image to it). An empty flash is a valid jffs2 file system, so 
if this works, but mounting the partition with an image in it doesn't, 
there could be something wrong with your image.
