Yes, only small changes in the protocol modules regarding (un)registration.

Getting the original modules work with pata_parport (like in 1st preview) required some hacks that break paride (disabling EXPORT_SYMBOLs in paride).

Maybe the protocol modules can be moved (git mv) from paride and then patched? A copy would be better but there's no "git cp".
