I'm not the expert here, but off the top of my head you'll also need to deal with UEFI boot-time and/or runtime services, and you'll probably need to make your initial boot binary be a PE UEFI executable. I'm sure there's probably more - I'd look at the Linux UEFI boot path. -- Steve McIntyre, Cambridge, UK.
