Just to clarify a bit - my point was not to suggest that port is 
irrelevant, or that the FreeBSD should not go there. In fact I believe 
on contrary from what I know sun4v is good as a testbed for the future 
of multi-processor architectures today - definitely we will see ever 
increasing number of cores in commodity Intel/AMD servers in few years 
from now. So that in that sense sun4v work is very important if the 
FreeBSD project wants to keep ahead of things, not catching-up later.

However, realistically immaturity of the port as well as scarcity of 
hardware limits number of users severely. Therefore, absence of PRs 
should not be surprising to anyone.
