+	  This driver adds support for the ACPI-WMI (Windows Management
+	  Instrumentation) mapper device (PNP0C14) found on some systems.
+
+	  ACPI-WMI is a proprietary extension to ACPI to expose parts of the
+	  ACPI firmware to userspace - this is done through various vendor
+	  defined methods and data blocks in a PNP0C14 device, which are then
+	  made available for userspace to call.
+
+	  The implementation of this in Linux currently only exposes this to
+	  other kernel space drivers.
+
+	  This driver is a required dependency to build the firmware specific
+	  drivers needed on many machines, including Acer and HP laptops.
+
+	  It is safe to enable this driver even if your DSDT doesn't define
+	  any ACPI-WMI devices.
