In 2.2, you can mark whatever in modules as initialization only and it won't be honored. I was trying to get the patch which actually made it work into the kernel several months ago (it was written more than a year ago), but Linus said it is for 2.3. And in 2.3, I and some other people would like to redesign all the stuff related to buses (PCI, SBUS, ...) and module initialization, so that e.g. it would be possible to insmod a module and tell it to drive one particular device, not all of them as it is done now. Also, it should be possible, while a module is loaded, to insmod it again for a different instance of the device. That would mean putting into the kernel only the initialization sections, calling the init routine with appropriate device handle and discarding it again (the rest of code and data would be taken from the already running module).
