I'm not aware of any "memory mapping problem" with internal video, but
here's what's happening:

The GENERIC kernel will look for either an internal or nubus/external
video to use as the console.  Whichever one it finds first will be
selected as the "console".  And if you have both, it will always find
the internal video first.  So even though you don't have a monitor
connected (using paper clips instead) NetBSD thinks you have a monitor
and that's what it will select.

You have two choices:

1. Remove the paper clips, and run the risk of hitting whatever mapping
   problem there might be, or

2. Compiling your own kernel from sources, and don't tell it to look
   for internal video.
