I snagged the difference, both machines boot identically until:
...normal boot...
  Successful SIA initialization
  /usr/sbin/autopush: Can't push requested modules on STREAM for entry 36
  /usr/sbin/autopush: Device (6,-1) already configured
  Streams autopushes configured
  Configuring network

nterface: mc0
 Loading LMF licenses
 Combine OPEN3D ALS-NQ-2000NOV14-640 with OPEN3D B0700-CAMPUSWIDE-2305
etc.
Both machines have memory channel cards in PCI slot 3 which show up 
at the begining of the boot.  I wonder if my one MC card has gone bad?
I can run netsetup by hand and all the rest of the tcp/ip stuff comes
up fine.
thanks,
jim
