+	  This enables support for the Philips UCB1400 touchscreen interface.
+	  The UCB1400 is an AC97 audio codec.  The touchscreen interface
+	  will be initialized only after the ALSA subsystem has been
+	  brought up and the UCB1400 detected.  You therefore have to
+	  configure ALSA support as well (either built-in or modular,
+	  independently of whether this driver is itself built-in or
+	  modular) for this driver to work.
