+ * The firmware is non-free and must be extracted by the user. Tools to do this

+	  This driver enables a watchdog capability built into the

+	  processors.  This watchdog watches your kernel to make sure

+	  a certain amount of time.
+
+	  You can compile this driver directly into the kernel, or use
+	  it as a module.  The module will be called geodewdt.
