kloader(9) currently cannot work on archs where you don't have a memory
space where va =3D=3D pa is true.

So, kloader(9) on i386 is possible barring that you:

  1.  change the kloader inner workings lightly so it copies the new
      kernel into a set of regular virtual addresses.
  2.  create an api (in uvm or through some hack of your choice, it can
      be made better later) to easily get the few pages you need for the
      bootloader that verifies pa =3D=3D va.
  3.  pass the set of physical addresses where the kernel has been
      copied to said bootloader.

At least, that's my recollection of when I looked at it for hpcarm.
