Any idea of the last kernel version that worked?  So I know I can count on
that as a reference?  I have the 2.2 pre7 from BSE, but there have been a
few changes since. ;^)

It appears the image (bootwrapper) needs to be completely self-contained,
and needs to understand how to read the flash parameters.  That's on my
list.

Understood.
