That's my understanding as well.

Agreed. However larger SPARC systems can, I believe, be divided into 
multiple domains, and larger IBM PPC systems can be partitioned into 
LPARs. I don't have practical experience of either of these 
technologies, but if Leonardo's been told "there's a system on its way 
to you and we expect you to use its virtualisation facilities" and if 
it's non-x86 then that's the sort of thing he's likely to have to 
contend with.
