Yeah, I believe this is the right commands and should work.

Yeah, and even on NOR.

Nope.

Hmm, JFFS2 is complaining that you feed it with a flash which is neither 
empty nor contains a valid JFFS2 FS image.

Try to avoid using -j ans see what happens. You also may try to enable 
JFFS2's debugging prints.

I personally have never used OneNAND, and AFAIK it is rather new in MTD.
