I have an Atom C2758 that I could test it on, and I would like to > test it. I just need to create a head BE first. So C2xxx is the one device where the driver isn't functional yet. :( It has its own platform code and so is the oddball among the devices supported by this driver. I just got access to a C2758 this weekend and have been debugging a firmware initialization issue, so hopefully it'll be resolved in the next couple of days, after which I'll follow up.
