MAX_CHUNK_SIZE must currently be 64 -- the adder doesn't handle 32-bit
(and probably never will -- it may be easier to write a separate 32-bit
version, and let the EU_IMU wrapper entity include the appropriate one).

The stages are already separate processes (that is, they're easy to
separate), and the pipeline register is concentrated at the end of the
first stage.

That would mean that we have to use a register component again (I'd prefer
a concurrent procedure, because it would make the code more readable, but
some synthesis tools don't grok edge expressions in a procedure. *argh*).

Didn't I mention that it won't compile? ;)   Before you try again,
install the latest libelf pre-release from my homepage; the URL is
