I also figured out that for some of the words to become available I have to actually execute a real boot - not sure why.

Here's the output from "do-boot" once I turn on debugging for Solaris Nevada B127:

Can't mount root
 Aborted.

Again, not sure why it can't mount-root, but that seems to be the issue.  And, here's the output from a debug do-boot for Solaris 9:
