+          This driver provides support for extra features of ACPI-compatible
+          ASUS laptops. As some of Medion laptops are made by ASUS, it may also
+          support some Medion laptops (such as 9675 for example).  It makes all
+          the extra buttons generate standard ACPI events that go through
+          /proc/acpi/events, and (on some models) adds support for changing the
+          display brightness and output, switching the LCD backlight on and off,
+          and most importantly, allows you to blink those fancy LEDs intended
+          for reporting mail and wireless status.
+          
+          All settings are changed via /proc/acpi/asus directory entries. Owner
+          and group for these entries can be set with asus_uid and asus_gid
+          parameters.
+          
+          More information and a userspace daemon for handling the extra buttons
+          at <http://sourceforge.net/projects/acpi4asus/>.
+          
+          If you have an ACPI-compatible ASUS laptop, say Y or M here. This
+          driver is still under development, so if your laptop is unsupported or
+          something works not quite as expected, please use the mailing list
