I think, you must first disable this setting because S5 is the default
behavior when pressing the power button, it calls /etc/rc.shutdown.
hw.acpi.power_button_state: S5
Disable it with sysctl hw.acpi.power_button_state=3DNONE and add this
line to /etc/sysctl.conf. And then maybe the power button will be
released for an other purpose?
Kind regards.
