Autif, All good questions. I'm traveling right now and don't know the answers off the top of my head. I'd try module_autoload and see if that does what you want. I'll be back briefly next week and then off to ELC. I should be able to assist next week though if you don't resolve this on your own. I don't believe this is documented. We need to resolve that. The "how do I" is a reasonable start, but ultimately it needs to be in some combination of the BSP Guide, the Kernel Arch manual, and the Developers Manual.
