Let's start a discussion if /dev/kmem is worth keeping around and
fixing/maintaining or if we should just remove it now for good.

The last time I used /dev/kmem was in 2003. While in Germany, my home
firewall (in the US) got rooted. I could ssh into the box but had no way to
shut it down because the rootkit took over all those commands (luckily it
still allowed me to become root). I finally killed the box with:

 # ls -lR / > /dev/kmem

 ;-)

But today I have other means of killing the box (or at least crippling it).
Thus, it's obsolete in my book.
