Hi,

g-p-m invokes HAL for suspend / hibernate, so I suspect this bug report
really belongs to hal. To be sure, you should be able to invoke HAL
manually for suspend;

        dbus-send --system --print-reply --dest=org.freedesktop.Hal 
        /org/freedesktop/Hal/devices/computer 
        org.freedesktop.Hal.Device.SystemPowerManagement.Suspend 
        int32:0

(It should be launched as a single long command)
