It depends. The hard thing with linker scripts in knowing what is
incidental and what is required by existing linker scirpts.

So far I the things I think are required

* Two PT_LOADs. Unfortunately the linker scirpt is in charge of
aligning, so it has to know where a PT_LOAD start.
* As a consequence of the above we have to place orphans so that they
don't require more PT_LOADs

Do you know of some requirement that is not currently met?

Cheers,
