Well, first off, the kernel loader ignores the program header, which
will amost certainly break any non-DSO.  It looks like the loader is
extremely incomplete.  Would it be possible to use it to just load a
userspace ld.so, and let that to the real work?  Is the mmap code in the
kernel good enough?  Just speculation here, for the moment.
