This seems to be fine to me :-)

Now, you'll want to run the 'fconfig' command to set up your board's
environment, including setting the ethernet hardware address (ESA)
and IP selections.

In any case, you should be able to treat this just like you did the
simple stubs.  Connect via GDB and you're off.

Did you set the startup type to ROM?  This is not forced for RedBoot like
it would be for simple stubs (I forgot to mention it).
