You would basically have to recreate most of the second stage boot, and start thwacking up a virtual address space. At the very least, you would need to modify locore.s. NT doesn't return to real mode for anything; that's why it doesn't have the VM86 based drivers available, as Windows 95 does, that would allow it to run on all PC hardware.
