All your commands are failing for the same reason - load-base points to
memory which boot command can't use. Write printenv to find where
(actually you will see more variables, not just load-base, and both
current and default values), and eventually with setenv load-base
0xabcdefgh you could change it.

As I know nothing about your hardware (actually being new to powerpc
platform too, working with some Apple hardware a bit), I have no other
recommendations for you. There could be even some memory problem, but
this is just a wild uneducated guess.
