Hmmm...not really working for me.  I don't know that I'm actually at the "ok" prompt - I see the word "ok" output to the screen, but the prompt is actually "0> " and not okay.  When I try "see do-boot", I get "do-boot: undefined word."  Furthermore, almost none of the other commands work, either - get-bootdev, load-pkg, etc., all return "undefined word."

Just to make sure I didn't leave anything out before, I'm running qemu-system-sparc64 (from the Qemu git repo), using OpenBIOS built from the svn repository.  If there's something else I should be trying, please let me know.
