Those two lines are only a warning and you can shut it up by creating a 
/usr/X11R5/lib/X0screens file and putting "/dev/grf0" in it.

Don't know whats happening here.  I can't speak about the NetBSD port directly 
but certainly the 4.4bsd version its derived from handles -query with a remote 
host as I use it here every day.
