Oh, that's interesting. So this is what I currently see in OpenBIOS:

So the /memory and /virtual-memory nodes look correct - but the "mmu" 
property in /chosen is set to point to "/SUNW,UltraSPARC-IIi/mmu" which 
doesn't actually have any properties set!

Does anyone know what this second CPU MMU node is used for? Should the 
/chosen "mmu" property point to /virtual-memory instead? Or should this 
node be an exact copy of /virtual-memory?

ATB,

Mark.
