Luckily (after half an hour of googling) I found this in gnome power manager mailing list.
Have a look at /etc/dbus-1/system.d/hal.conf and change the at_console="true" line to user="username_of_you". Then restart dbus.
And that made the trick :D
(I also added myself to powerdev group... you never know ;) )
adduser [myuser] powerdev
