I found my original one in my random cape pile. It's the audio rev a, with the ac3106, i'll give it a shot tomorrow. In "theory" you'll be able to get "most" support from the dtb-rebuilder using the 3.14.x branch for your 3.16 kernel. There's new things like pm, pruss, that won't work as that is out off tree stuff.
