Can you post the kernel messages for your boot, so we can reference it 
in the Debian Wiki? Maybe by comparing them to what was posted about a 
M3000 with SPARC64 VII on [1] and SPARC64 V on [2], we can conclude if 
support for SPARC64 VII+ is any better than for those other processors.

You don't happen to have a SPARC64 X based system for testing? I think I 
never saw a dmesg from such a system, too.

I went through the history of changes and the one that adds the 
information about SPARC64 processors ([3]) was done by an Alex McWhirter.

Checking my email archive I actually even asked him (via 
[email protected], though not sure if that is the correct 
address) exactly about this change, but never got a reply IIRC.
