+        help
+          This driver installs a global ACPI Operation Region handler for
+          region 0xA1.  AML methods can use this OpRegion to call arbitrary
+          native firmware functions.  The driver installs the OpRegion
+          handler if there is an HPQ5001 device or if the user supplies
+          the "force" module parameter, e.g., with the "aml_nfw.force"
+          kernel command line option.
