Hmmm, I've just downloaded this and all thats in the archive is the updated kernel. So since gph didn't use any closed source modules, we can now demand the source code to the modified kernel, including the source code to there drm

Also, if they refuse, we can sue them

And if they are using the sd card as protection, its even more fun. They can be sued if they don't release the source code, and sued if they do.
Sounds like typical a GPH screwup to me! Every other company would put there drm stuff in a module, so they could release the source to the kernel, but keep there drm proprietary.
Ho hum..
So, who wants to send of the legal letters?
