[Rack] Thin clients

[Dr. Jesus]

The first one has replaced the old door computer.  The video
configuration still needs a bit of work, but you can poke the screen
and open the door just fine.

I'm building a replacement netboot environment for it now which should
fix the video problem.  I'm also going to add hooks to remote the X
clients from stallion, since these machines are quite a bit slower
than the laptops they're replacing.
