Catching standby/suspend/hibernate/battery-down events by a non-root user process

[gautham gggg <gauthammail1984 yahoo co in>]

Hi all,
   I'm using SLED 10 with gnome 2.0. Is it possible for non-root user process to catch standby/suspend/hibernate/battery-down events. As i have to stop these processes on those events. If possible how do i do that?

Regards
