Smells like there's yet another issue dealing with interleaved chips
(already worked out two and I thought all of them were fixed).

wich version of jedec_probe.c, v1.26 or later?

I'm likely the one to blame.  Unfortunately I can't look at this until
tomorrow - sorry.  Let me know the version of jedec_probe.c you have and
also send me any relevant kernel messages with MTD_DEBUG_LEVEL set to 3.

I don't even have time to look at the data sheet right now, but wanted
to let you know that someone's listening and interested in fixing this.
