is an initial stab at solving PR/35348 for NetBSD 6.0.  After 6.0

Open Firmware 3.x and newer often won't setup the console if you don't
drop to a prompt, and
.Nx
doesn't know how to setup the console itself.
To get the system to boot when you have auto-boot? set to true, you
can try this workaround.
First, try one of the following commands:
.sp
.Dl setenv boot-command \*[q] screen\*[q] output boot
.Dl setenv boot-command ." screen" output boot
.Dl setenv boot-command ." Booting NetBSD..." cr \*[q] screen\*[q] output boot
.sp
You should follow the command with:
.sp
.Dl reset-all
.sp
This will cause Open Firmware to output some text to the screen prior
to booting, thus forcing it to setup the console.
.Pp
Otherwise, you need a serial console.
