+	  module will be called rng-core.  This provides a device
+	  that's usually called /dev/hw_random, and which exposes one
+	  of possibly several hardware random number generators.
+
+	  These hardware random number generators do not feed directly
+	  into the kernel's random number generator.  That is usually
+	  handled by the "rngd" daemon.  Documentation/hw_random.txt
+	  has more information.
 
 	  If unsure, say Y.
