Good stuff!
Yesterday I have managed to compile the kernel but building the hybris failed at the beginning. Fortunately I have found a good place where from some kernel patches are available and in the hadk-faq there is a hint for why the hybris build failed. Today, I will try again. Once I have a build that I can install and test, I will open a topic for that because don't want to litter this one with my S7 troubles.

By the way, from my github repo have you managed to get the files what you need for testing the OBS? If not, please let me know what you need and I will send over.
