thorpej f363b73f87 Add support for the AlphaServer 2100 (Sable) and the AlphaServer 2100A
(Lynx), written from scratch by me over a year ago, but never committed
to the tree because there was a bug I could never quite find.  I have
fixed a few problems in the code, but still don't know if that bug is
quite fixed.  Since I don't have access to the hardware directly, I'll
have to call for testers again.
