Well, you need to have your devices working earlier to eg boot from PCMCIA. Thus you need a way to safely switch from operation without user space support to operation with user space support. You need to lock the bus so that you don't configure devices that have been replaced and after that unlock the bus. You need at least a few sysctls to do that.
