+		This number is indended for use in sample code, as
+		well as a general "example" device number.  It
+		should never be used for a device driver that is being
+		distributed; either obtain an official number or use
+		the local/experimental range.  The sudden addition or
+		removal of a driver with this number should not cause
+		ill effects to the system (bugs excepted.)

+		This range is currently assigned as part of the
+		local/experimental range.  However, because of the
+		Linux way of setting a limit on the highest device
+		number in the system, currently set at 63 by default,
+		I am considering changing the local/experimental use
+		to 60-63, 120-127, 240-254.  If you are currently
+		using the range 224-239 and such a change would pose a
+		problem for you, please contact <hpa@storm.net> as
+		soon as possible.
