  Add

acpi_ibm_load="YES"

  to your /boot/loader.conf (or compile this module into the kernel)

  Add

  notify 0 {
        match "system"          "ACPI";
        match "subsystem"       "IBM";
        match "notify"          "0x07";
        action "/full/path/to/script";
};

  to /etc/devd.conf
