I have a similar setting, but it requires X, WindowMaker and a
Sun Type 6 USB keyboard. :-)

Short explaination: I have assigned the command

	xterm -class SHUTDOWN -fg black -bg red -e "shutdown -p now ; read DUMMY"

to the key combination Ctrl+Alt+(I) - the "switch off" or "moon"
key on the top right. This combination is impossible to press
accidentally. (Without Ctrl and Alt, this key closes the X session
and leads back to xdm for login.)

You could add a clickable menu entry or desktop icon with this
command, but make sure it's not accidentally clicked. :-)

If your father is already logged in, he could "shutdown -p now"
(or using an alias) from an xterm. He needs to be in the wheel
(or at least operator?) group for this.

What about pressing the power button on the machine itself, it
should perform a "shutdown -p now" (shut down and power off).

By tht eay, the key you're refering to is named "System Request",
or SysRq.
