I wasn't sure if Sun had rebadged it - but obviously not.

http://wikis.sun.com/display/FOSSdocs points to
http://mediacast.sun.com/share/barton808/Neptune_PRM1.4.2o.pdf I
haven't looked at it closely enough to determine whether you could
write a driver from it.  (And, at this stage, I don't have time to
write the driver myself, though I'm willing to help debug it if
someone has a alpha or beta one lying around).

The FOSSdocs site points to the T2 architecture supplement for the
T2 NIU.  I haven't gotten to that document yet.

Please excuse any delays as the result of my ISP's inability to implement
an MTA that is either RFC2821-compliant or matches their claimed behaviour.
