I am also not an x86 expert, but I think that jmp _does_ take an
immediate offset (as your second example demonstrates) or absolute
address <http://en.wikipedia.org/wiki/JMP_(x86_instruction)>. The
hotel wireless is slow enough here to prevent me from downloading
the manual linked on that page to figure out exactly what is
possible with jmp.
