I assume you researched it already, so I won't get
into asking if you are
sure the 7200 will go into open-firmware. I thought it predated OF. I
didn't think they started that until PPC's... but I'm not really sure
(and seeing as the 7200 is PCI, it is a good candiate to be an early unit
with OF).
According to this link, it states that OF on the 7200 doesn't
drive the display and that a serial cable must be constructed to
access it by terminal. It doesn't give specifics on the connection
though.

There are also other links there that may be useful. It
looks like OF on the 7200 has quite a few bugs.
