Generic LDOM Configuration not working on Sunfire T2000

Hi,

I am on the above mentioned hardware running OpenBSD 70 -stable.
Someone mentioned in another thread that LDOM problems on a T1000 were
solved by upgrading the firmware to 6.7.13. My firmware version is
close enough - 6.7.12, so I doubt that this has to do with firmware.

Anyway, while trying to follow the ldom man pages, tedu's LDOM guide
and/or the ldom guide in undeadly.org, the setup fails: after
reaching the point where I see the new logical domain marked as 'next'
after running #ldomctl list, I halt the system and reset the ALOM as
instructed. It seems until that point that the new configuration has
worked and was indeed dumped to non-volatile storage of the SP.

However, the only thing that happens is that the machine does not
reboot to my primary domain. Stuck in the openboot prompt, I load
the generic kernel for the primary domain, which then boots...but
then #ldomctl status only shows the primary domain, nothing more.

What might I be missing here? As stated before and I reiterate, I
am really following instructions step by step - I even went so far
as to name my additional domains 'puffy' and 'salmah' just in case.

Thanks in advance for any useful hints.
