I don't see anything wrong in the code (`(%esi,%eax)' is indeed not a valid
16 bit base/index, but it AFAICT it isn't meant to be).

However, your binutils are a bit old.  Perhaps this is a bug they fixed ?

Anyway, maybe this solves the problem for you:

+       .code32
        leal    0x200 + data_start - data_next(%ebx,%eax), %eax
+       .code16

(please report if it does)
