Provided you have both a new userland and a new kernel, you'll also need
to create /dev/ipnat and /dev/ipstate, as well.  They have the same major
as /dev/ipl, and use minors 1 and 2, respectively.

This was an `oops' in the recent upgrade, and the fixed MAKEDEV scripts
should have already gone out via SUP yesterday.
