Hi,
I've created images [1] with kernel based one Fedora kernel package
which is reasonably close to mainline and Pidora userland. See README
[2] for more detailed information and installation instructions.
Both 3.14 and 3.15 (rawhide, with debugging) kernels are available.

The changes to packages and build tooling are available on GitHub [3].

Maybe someone will find this useful.
Thank you,
