Ok - so I finally have NetBSD running on this bloody thing...But, I can't 
get it to autoboot from ie(0)...it insists on using xy(0)...

This is SunOS 3.5, and there is no eeprom command on the thing...So, I 
tried plopping the following in a prom addr 0x19:
	69 65 0 0 0 

which translates to ie(0,0,0)

>b
Boot: xy(0,0,0)
Load: xy(0,0,0)boot
Boot: xy(0,0,0)vmunix

Sun UNIX 4.2 Release 3.5 (GENERIC) #1: Tue Dec 1 17:15:48 PST 1987

So, what am I missing here?

On the lighter side...

>b ie(0,0,0)
Boot: ie(0,0,0)
