I've created images  with kernel based one Fedora kernel package
which is reasonably close to mainline and Pidora userland. See README
 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 .
Maybe someone will find this useful.
