I've attached what I've got so far. This only fixes the LKM issues.
How important is adapting arlad to use these new opaque file handles?
Either way I think that would involve touching configure, something
I don't want to figure out how to do.

Perhaps I should, the lack of this feature is something I often gripe about.

Kauth is originally a Darwin thing, and it seems Elad took the liberty
to make the NetBSD implementation different enough to be frustrating
for folks needing to support both OSes. However, this also opens
the possibility that NetBSD could diverge more to support this,
assuming Apple is uninterested; but this would probably mean
more #ifdefs in already somewhat difficult to follow code.
Additionally, any change as large as this would surely not
be allowed into 4.0.
Oh, also, the changes I asked for to get stuff going on -current
caused an undesirable side-effect of breaking PAGs on earlier
NetBSD releases.
Looks like I have some more tasks I could be doing.
