Well, you could put .config in it too.

Frankly, a filesystem that:
- can be somehow linked with vmlinux and not separate like an initrd

- editable post vmlinux-linking

- gives files that can be accessed from request_firmware, acpi and
  friends even rather early in the boot process (i.e. well before any
  userland is allowed to exist)

- accessible post-boot through mounting of a special fs and/or /proc or 
something

would be quite useful.

This exists. It's called initramfs. Read the kernel code :)
