Sun Fire V480 compatibility question?

Hi guys and Marius, (sorry for the cc but you did bring up the topic so
I'm figuring that you probably know the most about this subject!)
I am just in the process of figuring out which Sun bridge I will need
for the Fire v480 server as a quote from Marius Strobl suggests this:
FreeBSD currently crashes on older models of V480 when attempting
to use an on-board NIC due to what appears to be a CPU bug which
needs to be worked around. It appears to work fine on later V480
equipped with version 7 Schizo bridges (that's just an indicator
and unlikely related to the problem) though, but FreeBSD 7.3 will
be the first release (besides the current stable branches) to work
with their changed firmware behavior. Linux doesn't seem to do any
better in this regard:
My supplier has given me an extract from the Sun handbook which doesn't
seem to show version 7:
<=501-5819-12: SCHIZO 2.2
>=501-5819-13: SCHIZO 2.5 August 2003
only available from
SCHIZO 2.5 April 2004
or ELE 1.1+
A bit of Google'ing however got me to this:
Version /Schizo/ Rev /7/ 2.5 6 2.4 5 2.3 4 2.2. Symptoms. Should the
described issue occur, /Sun Fire/ 280R, /V480/, V880 and Netra 20
systems may encounter a FATAL *...
* FreeBSD has been adopted to the changed firmware of newer Sun Fire
V480 (those equipped with version 7 Schizo bridges) and has been
reported to now run fine on these. The necessary change will be
part of 7.3-RELEASE. Unfortunately, using the on-board NICs in
older models of Sun Fire V480 (at least those equipped with version
4 Schizo bridges) under FreeBSD still leads to the firmware issuing
a FATAL RESET due to what appears to be a CPU bug, which needs to
be worked around.
Taken from the Sparc64 part of this page:
What I can understand from all of this is that the version 7 is actually
a revision 7.... so any of the bus versions listed above in the table
will work as long as they are revision 7 or later?
Is this the case, have I understood correctly??
