+	  Enable support for the Omnikey CardMan 4040 PCMCIA Smartcard
+	  reader.
+
+	  This card is basically a USB CCID device connected to a FIFO
+	  in I/O space.  To use the kernel driver, you will need either the
+	  PC/SC ifdhandler provided from the Omnikey homepage
+	  (http://www.omnikey.com/), or a current development version of OpenCT
+	  (http://www.opensc.org/).
