Two more questions...

  How do I get the G4 to automatically boot NetBSD? I tried
setting the appropriate OF variables, and indeed it loads
NetBSD when I then type "boot", however, on next boot the
variable has reverted to its previous value. 

  How do I get into DDB? The "programmer's button" doesn't
seem to have any effect. (I have here a hard hang after accessing
a USB-scanner so I wanted DDB to find out where it hangs)
