There are at least three other steps:

	* Update the assembly (.s and inline asm) to a slightly
	  different syntax that's compatible with the ELF assembler.

	* Make sure that there are no dependancies on the structure
	  packing:
		a.out: struct { short a; long b; } is 6 bytes
			and &b is struct base + 2.
		ELF: struct { short a; long b; } is 8 bytes
			and &b is struct base + 4.
	  (IIRC ;-)

	* The booter needs to understand and load an ELF kernel.  This
	  can probably be avoided in the short term by using objcopy to
	  convert ELF -> a.out just for booting.

I think that's it.
