suspend on fc5

[William John Murray]

 Hello all,
           I would like to try out suspend (ramd and disk) on FC5T1.
It looks like gnome-power-manager is the way to go?

 I installed gnome-power-manager.i386, libnotify.i386,
notify-daemon.i386 and hal-gnome.i386 but something is still
wrong. 
gnome-power-manager --no-daemon
responds:
 ** (gnome-power-manager:3662): CRITICAL **: HAL does not have
PowerManagement capability

   Can anyone suggest what might be responsible? I am woefully
hal ignorant.
         Thanks,
           Bill
Ps Typing gnome-power-manager by itself just does nothing.
