+
+         This kernel driver requires that the matching userspace driver
+         handles interrupts in a special way. Userspace is responsible
+         for acknowledging the hardware device if needed, and re-enabling

+         ports instead of memory mapped I/O. In order to make it
+         possible for UIO to work with this device a utility, uioport,
+         can be used to read and write the ports:
