Why bother? We can have userland code running before any device drivers
are initialized. And have access to
* all normal system calls
* normal writable filesystem already present (ramfs)
* normal multitasking
All of that - within the heavily tested codebase; regular kernel codepaths
that are used all the time by everything. Oh, and it's portable.

What's the benefit of doing that from EFI? Pure masochism?
