Jan,
	This is a somewhat oblique hit on your request, but at the 1981
NCC, there was a paper presented under the auspices of AFIPS, entitled
"The design and implementation of a new UNIX kernel", by Charles Crowley
of the University of New Mexico at Albuquerque. This is published in the AFIPS
conference proceedings, volume 50, pp. 265-271.
Specifically, he had rewritten v6 Unix as a message-passing kernel. He claimed
that it worked--albeit more slowly, on a single-processor system, than the
USG v6--and mentioned that one of its applications would be a multi-processor
system. He also indicated in his actual talk that he would be taking the idea
a bit farther, and actually trying a multi-processor configuration.
