I take this back. /etc/acpi/power.sh is run regardless of gnome-power- manager. It may be the case that /etc/defaults/acpi-support does not have ENABLE_LAPTOP_MODE=true turned on.
There is a related bug, where the acpi-support doesn't run on suspend/resume because gnome-power-manager is running. Because of that, laptop-mode isn't run.
