Roughly under 5.0.x etherboot had to be loaded at a specific address
to run properly.  So loading the .rom image was the only way to get it
to work.  Under 5.1.x etherboot now has the relocation code in it, so it
now handles being loaded at an arbitrary address.  So all that has to
be done is to jump to the start of the .img file.

I obviously forget to take out a couple of unnecessary checks.  When
I have a moment I will take a look.  But it should be a fairly simple,
operation to make it work.
