Have you tried using a recent [mainline] kernel?  I'm running a
mostly-vanilla 2.6.29 kernel on a custom MPC8313-based board with a
large-page (2k) NAND, and YAFFS gives me no errors when used similarly
(using erase & populate, not mkyaffs2image).  It flags bad blocks, of
course, but they're real - maybe 5-10 total on a 1GB chip, and they're
detected at mount time (it sounds like your errors are occurring after
that).

It might be worth taking a few minutes to build a more recent version
and see if it makes your problems go away, if that's possible.
