I'd like myself to see it working on Odroid c1, but the fact that hardkernel guys don't have it supported in upstream kernel doesn't help (and just having it compiling doesn't work on my side -yet- )
I have tried the kernel from https://github.com/hardkernel/linux in September and I think it worked fine on my Odroid C1 except for the HDMI output. So, I didn't include it in the github repo for RootFS Build Factory. The kernel presently in the repo is one borrowed from Ubuntu, which supports HDMI output. One point I should probably mention is that I cross compiled the kernel and I am guessing that you built it on an arm node.
