On my PM4400/200, with BootVars, I have changed input/output-device to ttyb,
and ... It works..
I have copied NetBSD-daily/20020609.../boot.fs onto SCSI disk and boot from it. 

More important thing is: with input/output-device with kbd/screen, it stops 
after start=0x800000 line is shown.

PM4400 has very strange setup on keyboard. PS/2 connector is not installed
but internally and Open Firmwware wise ADB and PS/2 are muxed. To be worse,
OF probes PS/2 first and it says something is connected there  (just guess,
See akbd0 and akbd1 lines below). This situation is little bit different
in StarMax. PS/2 keyboad connector is there and probably it is probed and
saying nothing is connected there.

(But why the older src works, yes.  I have no idea at the moment.)
