-	  This is useful if you are developing a PnP driver or troubleshooting.
+	  Say Y here if you want the PNP layer to be able to produce debugging
+	  messages if needed.  The messages can be enabled at boot-time with
+	  the pnp.debug kernel parameter.
+
+	  This option allows you to save a bit of space if you do not want
+	  the messages to even be built into the kernel.
