Assuming you want to know whether the server was rebooted (as opposed to
whether a user invoked a given key combination), adding something
along the lines of the following to root's crontab(5) should suffice:
@reboot echo "`hostname` rebooted" \
| mail -s "`hostname` rebooted" gilles at example.org
