The only problem being that when someone pointed out that it was _not_
just the processor documentation then they were promptly flamed and
told to got write the code themselves.  It looks like the
documentation for the hypervisor API is there which should be enough
to get things going.  Even if it is not:

<http://cvs.opensolaris.org/source/xref/on/usr/src/uts/sun4v/>

may help out with some clues.  So, there is a lot more information out
there than you may have been lead to believe.

Having said that, one wonders why the hell anyone would want to run a
single threaded, big lock style kernel on hardware that is designed to
run highly multi-threaded software.  Performance will suck, Sun will
tell you this.
