Add some text to "Common Problems" about Open Firmware 3.x not
setting up the console and how to work around the problem.  This
is an initial stab at solving PR/35348 for NetBSD 6.0.  After 6.0
is released, a better solution can be done for 6.1.

+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.
