Ok, so it was sort of a false alarm.  Through my own stupidity, I was
running the wrong nfsd, and having corrected this problem, I can now
use NFS between 1.3 and 1.2G systems, and non-NetBSD systems and the 
1.2G and 1.3 systems.  1.2/1.1B/1.1_ALPHA/1.2_BETA(this one logs me out---
the shell segfaults) systems still will not talk to the new NFS servers, 
however.  The 1.2/1.1B setup is a production cluster of some 30 systems 
with varying setups (four different architectures), and I really don't 
want to upgrade them to the new alpha system unless it's strictly and 
absolutely necessary...
