IIRC, JFFS2 will pad the node to the correct size so write failure
shouldn't be an issue.  I could be mistaken, it's been a while.

Is this a problem you are currently seeing, or is this all just
theoretical?  To my knowledge, there are no other NOR ECC flash chips
out there.  Even if there were, support would need to be added to MTD
before they could be used.  We could adapt JFFS2 at that time if needs
be.
