Hi again,

The g-p-m FAQ mentions something about this,

        My monitor is broken and treats DPMS standby and off states as 
        'no-signal' which leaves the monitor powered on.
                
        You have to change the dpms suspend mode gnome-power-manager
        uses.
        Open gconf-editor, and then change the
        keys /apps/gnome-power-manager/ac_dpms_sleep_method 
        and /apps/gnome-power-manager/battery_dpms_sleep_method to 
        one of the modes that work, e.g. standby, suspend or off.

The dpms problems with apm is probably a kernel problem, but this should
at least let you work around it.
