Which one? :)
Daniel had success using the exact patches that are in the Fedora kernel tree.

Hm... What did "some refactoring" look like exactly? :) I think that what Daniel is running wound up matching what's in Fedora 100% (aside from the one extra patch that sets the name in the device struct properly, but that isn't strictly necessary if you have only one hdpvr). I'm currently at a loss as to what else it could be.
