Not even serial console works here. But I debugged the problem today:

First, when working with physical console, checking for device_type property
"display" fails on the Pegasos. It is called "bootconsole". Additionally,
when the pckbc driver is missing, cninit_kd() would just return, instead of
falling back to the ofwbootcons.

Second, when using a serial terminal, the check for the name-property
"serial" fails, which is "failsafe" here. IMHO this check is not needed at
all, because it is a fallback to the ofwbootcons.

I fixed both with the following patch, giving me output with physical and
serial console on the Peg2:

And, it seems to me that printf() is pretty useless in this early stage. It
doesn't generate any output when anything goes wrong. Maybe we should think
about using OFPRINTF instead?
