Yep....I have some patches and someday I may fix it.

Since it won't work properly as a module, I would prefer you didn't
do this.  One of the reasons the CPM drivers aren't modules is there
are configuration dependencies built into the drivers.  You don't
have the flexibility to arbitrarily select any I/O configuration
at any time, the drivers have to know what may be conflicting and
avoid these configurations.  While there is an academic challenge
to make this extremely flexible, I haven't seen any production value
to this feature in use by people building real products.  If you
really need the driver, you have to build it in with consideration
of other drivers.
