Well, Sun Microsystems did give me a brand new Sun Fire T2000 to play with 
back in 2006 when I was participating in the CoolThreads Contest:

(I created the vZOOM project)

I kept it for about two years and then sold it. Unfortunately, I don't have 
access to a SPARC now.

Humm. Have you had a look at the relevant source code for OpenSolaris?

AFAICT, they implement everything you need.
