Yes, that seems correct.  I assumed, from your prior posting that
the only setting was the vfs.root.mountfrom= line.  On an amd64 host,
not having the zfs_load="YES" in the /boot/loader.conf file
gets exactly the "...failed with error 2." failure message.

Based on this further output, we know:
	- the first level bootstrap is loading
	- the "partition" code at the front of the ZFS filesystem is loading
	- the /boot/loader.conf file is found and read
	- the /boot/kernel/kernel file is loading off the zfs filesystem
	- the /boot/kernel/zfs.ko and /boot/kernel/opensolaris.ko files loaded
	- the /boot/kernel/geom_mirror.ko file loaded too

So, your machine is getting pretty close to fully loaded.
Knowing it is close doesn't actually get it booted, however.

I have not personally upgraded my sparc64 machines to a newer stable/9
in a couple of months either.  I suppose I will power one up and
start rebuilding...
