I looked into getting a 3.7 kernel up and going on the KNC board, but the diff between Intel's release and stock 2.6.34.11 has 70k lines. Much of that is kdb, but there's also a lot of low-level changes too, some of it due to the fact that KNC is 64-bit x86 but has no support for SSE (so you need to handle that properly or none of your userspace will run).
