This may sound like a stupid question, but why are you compiling the
modules statically?
I mean, it sounds to me like the perfect way to do what you want is to
compile the modules dynamically (you can store them in a an in kernel
initramfs if you want to keep them attached to the kernel binary for
ease of maintenance) and simply call a script that calls modprobe when
it's OK to load them?
Sounds a hell of lot simpler to me...
