patch: Add piuio-khack module

This module takes care of emulating the ITG 2 piuio kernel driver
hack. As a separate module, this can be hooked into any chain of
existing hooks providing a greater level of flexibility and
transparency.

+ * hardware the impact of this hack has become less and this introduces some
+ * sort of compatibility issue if you just want to run the games without
+ * having to depend on an additional kernel module handling this hack.
