There was that gratuitous change, and also the fact that they
changed what offset it gets the data from as well. Even more
annoying is that it prints out data that, at least on the Alpha,
is not a magic number, but varies with the executable.

The only appropriate solution I can think of relies on the kernel
giving the first 32 bytes or so and modutils doing some sort of

But the issue is non-pressing and I havn't gotten around to it.
