Of course that doesn't really help as there will be a dependency
between raid456.ko and pq.ko so you cannot avoid having pq.ko loaded
while using raid5.

It might make sense to create a raid6 module that just contains
The call to register_md_personality(raid6_personality) and some
linkage so that the code in raid456.ko can get to the code in pq.ko.

This is probably worth trying one the raid6 async offload stuff
stabilises.
