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...
