The clue to why this doesn't work is in the above line:  01badab1...
read that as "01 bad abi", ubldr failed on the first check of whether
u-boot provided the interface needed to do console and disk IO.

The only way to fix this is to use a custom-built u-boot that has the
CONFIG_API option set.  I've never tried that on an armv4/5 system, but
it should work.
