The GPL defines source code in section 3:
  "The source code for a work means the preferred form of the work for
   making modifications to it."

It doesn't address the question of _whose_ preferred form, but I think
that the form actually used by the author is a very good indication.
So if you entered the program with a hex editor, and fix bugs the same
way, then a hex dump is the source code.  (If the program is truly
write-only and not even the author can modify it, then I don't think
it can be free in any sense.)

In this particular case, if the firmware has a source that's not 
published, then putting the binary under GPL doesn't do anything
except make it unredistributable.  (The copyright holder is of
course free to do so, but no-one else can satisfy the conditions
of the GPL.)

We've had a similar case with smalleiffel once, which only distributed
the compiler as C files which had been generated from Eiffel sources.
This was fixed upstream after the problem was pointed out.
