This isn't really all too advanced actually. It's just a lot of steps, but for the most part the rules for compiling a kernel are same as documented all over the web. The only parts I needed to really learn were the flasher pieces. The SDK image in my thanks section is what really made this happen. With that, I saved time by not having to setup a debian/ubuntu machine/VM and do all the scratchbox stuff. Plus, I. could screw around with it when I was out and about. I literally did all the compiling on the N950. It takes more time compiling on the device, but feels more natural to me.
