Рассказываю по порядку.
Сначала создаются два пользователя remote-powerdown remote-reboot с
соответствующим шеллом )
Есть скрипт использующий expect:
[vitich@vitich poweroff]$ cat ssh_poweroff.expect
#!/usr/bin/expect -f
# usage: ssh_poweroff [terminal_address]
set PASSWORD "FiniSH+OK"
stty -echo
set ADDRESS  "[lrange $argv 0 0]"
puts "\n*** Halting the terminal $ADDRESS ***\n"
spawn ssh remote-poweroff@$ADDRESS
puts "*** Waitimg for 'assword' ..."
expect {
    "assword"	{puts "*** Sending password ***" ;  send "$PASSWORD\n" }
    timeout	{puts "*** Timeout ..." ;  exp_continue}
}
send_user "*** Waiting for terminal halt ... ***"
expect {
    "system"	{}
    "reboot"	{}
    "halt"	{}
    fail	{puts "\n*** SSH connect broken ***\n"}
    timeout	{puts "*** Timeout ..." ;  exp_continue}
}
puts "\n*** OK ***\n"

И есть два скрипта /usr/bin/rpoweroff и /usr/bin/rreboot
Почти всё позаимствовано у скрипта display2menu Миши Шигорина дабы
определить адрес x-терминала для выключения.

[vitich@vitich poweroff]$ cat rpoweroff
#!/bin/bash

debug() {
	[ -n "$DEBUG" ] && echo "$*" >&2
}

LC_MESSAGES=C
RESOLVE=/usr/bin/resolve

get_ip() {
	[ -x "$RESOLVE" ] && {
		IP="`resolve -s $HOST 2>/dev/null`"
		[ -z "$IP" ] && {
			debug "Can't resolve $HOST, using as is"
			IP="$HOST"
		}
		echo $IP
	} || {
		debug "No $RESOLVE executable!"
	}
}

[ -z "$DISPLAY" ] && {
	debug "No DISPLAY defined!"
	exit
}

HOST=${DISPLAY%%:*}
DISP=${DISPLAY##*:}

case "$HOST" in
	# I know it's a shell pattern... so 80% solution
	[0-9]*.[0-9]*.[0-9]*.[0-9]*)
		IP="$HOST"
		debug "X-terminal; IP: $IP"
		;;
	[a-zA-Z]*)
		IP="`get_ip $HOST`"
		debug "X-terminal; host: $IP"
		;;
	*)
		HOST="`hostname 2>/dev/null`"
		IP="`get_ip $HOST`"
		debug "Local display; $HOST"
esac

ssh_poweroff.expect $IP

Второй скрипт аналогичный.
Так вот если запускать из-под рядового пользователя из xterm - работает.
Прописал в ~/.icewm/preferences и /etc/X11/icewm/preferences
RebootCommand="rreboot"
ShutdownCommand="rpoweroff"
С /usr/bin тоже пробовал прописывать, хотя смысл? В консоли работает и без пути

Скрипт на expect не мой, я не программер :)
Может есть более правильное решение по управлению x-терминалом, но
стандартно при попытке перезагрузить или выключить комп с терминала он
просто секунд 10-20 висит, потом перезапускает gdm. А надо тушить.
