Tried 7.2..

[Dave McGuire <mcguire%neurotica.com@localhost>]

  Annnnd the NetBSD 7.2/pmax CD hangs on boot, at "scsibus0: waiting 2 
seconds fro devices to settle...".  I waited about 10mins.

  This is on a 5000/260 with a PMAGB-B.  The exact same thing happens 
in gxemul, emulating a 5000/200 with a PMAG-B.

  NetBSD/pmax is in pretty sad shape these days. :-(
