that gets me to scsibus0 device, but I have no idea how to get to
the device itself. I just booted out of OF and the scanner shows
up as ss0 (should be uk0, I think) so it was available.
ss0 at scsibus0 target 2 lun 0: <UMAX, Astra 1200S, V2.7> SCSI2
6/scanner fixed
I have set auto-boot? false in OF so I can always get to it with
no more hassle than rebooting and then running minicom from my
freebsd box. t'would be nice to be able to diddle OF parameters
from a login session.
