  To get the 4000/60 autobooting you have to have

 Most NetBSD's up to 1.5.2 garble the "HALT" setting on shutdown, so you
 should check this ("SHOW HALT"). Valid values are:
        3: Machine halts on powerup (Manual boot)
        2: Automatic reboot
        1: Automatic restart
        0: same as 2 
 Ah-hah! This one has HALT  set to 3. I haven't found any docs or online
info
about the nvram settings or post messages.
 Thanks, I'll try this.
