I don't think that's correct. consolehelper isn't that sophisticated,
AIUI, it can't vary its behaviour conditionally like that. I don't
recall 'reboot' _ever_ working the same way.

I just tested on two F17 machines and running 'reboot' as a regular user
happily reboots the system even if root is logged in at VT2, no warning
or authentication required. That does seem to make the 'protection' on
the graphical reboot button a bit pointless, but meh.
