Those are entire too old.

NAND + JFFS2 + 2.4 is not a supported combination.

Odd.  Do you have a diff from .31 to .32?

Well, 2.4 is supported but no new features go in that tree.  Including
NAND support in JFFS2.  If there is a bug in the 2.4 code that is
present in MTD/JFFS2 it can certainly still be fixed.

You might try your luck with patching the latest 2.4 kernel with MTD
CVS.  But be warned that quite a few things have changed, so you'd have
to essentially backport.

And keep in mind that it's not supported.
