I'll agree that it is not the ideal direction, but considering that
proper tracebacks for panics have been on the wishlist since before
I got my commit bit, then I think it is better than nothing.

It is interesting to note that most of the positive feedback I have
had on this is from people who are not in the heavy-duty kernel
development end of things, it is system administrators and people
who use FreeBSD for doing embedded things

I guess I'm getting a more specialized subset of panics reported then,
(but then, why would people send page faults to me until they suspected
some of my code ?)

I'm all for improvements, but I'm also under imminent danger of being
crushed if my TODO pile falls over, so somebody [tm] should beat me
to it.
