Absolutely, I'll help in any way I can. I'm currently content without
drm, however I would like to see it fixed for those who can't stop
playing crack attack (me!). I presently have zero knowlwedge about
kernel modules or drm, but I'm willing to learn and help with
whatever's going on with this.

Let me know what I can do and I'll do what I can :)
