I'm not sure this is what you need (I didn't follow the thread from the
beginning), but you can edit your /etc/inittab and change action on
CTRL-ALT-DEL from reboot to halt. This is what I'm using on a couple of
printer servers: their BIOSes can do without monitor, but cannot without a
keyboard ('No keyboard present. Press F1 to continue.' ;-) So I had to
leave keyboards attached, but with this setup I can easily shut them down
without using ssh/telnet/anything. Currently I plan to remove a PCB from a
keyboard and attach a single key which will do CTRL-ALT-DEL. With this key
on the case I will not need to attach separate keyboard to the box!
