 From http://www.netbsd.org/Documentation/bootcd.html#netbsd_mountimage :   

-----------------------------------
  vnconfig -c vnd0 output.iso
  mount -t cd9660 /dev/vnd0c /mnt

Please note that on i386 systems, you should use /dev/vnd0d instead of /dev/vnd0c.
Now you can cd to /mnt and explore your newly created CD image.
To unmount the image, do the following:

  umount /mnt 
  vnconfig -u vnd0

-----------------------------------

If that still fails, try as root (might be a permission thing).
