This is not part of my scheme.
The module loading will run with existing module loading privileges,
the "allowed capability" bits will be passed along back into the
kernel at module load time (via modprobe arguments or similar)
and validated by the kernel as it walks the ELF sections anyways
to perform relocations and whatnot.
