Darren Moffat put up some good posts when the code was initially introduced:

I don't believe encrypting the root volume is currently supported, so
pre-boot stuff doesn't apply. (Please correct if I'm wrong here.)

That is correct you can't currently encrypt the root/boot file system. This is because neither OBP or GRUB 0.97 have any knowledge of ZFS encrypted file systems and how to get keys for them. GRUB2 has support for encrypted ZFS file systems already.
