How does the PCMCIA subsystem work on FC5? Who is responsible for loading modules on demand?

[Vini Engel]

Hi guys,

I was wondering if someone could point me to the documentation here or 
give me some more information on this. I would like to understand how 
the PCMCIA subsystem works on FC5, what triggers the start-up scripts 
when a card is inserted/removed and how the module is loaded. 
Particularly how it decides which modules to load for that card and how 
I would tell it to load an alternative module instead. My understanding 
is that udev is responsible for that but I am not sure how it work.

Similarly, I would like to understand how the modules for the several 
peripherals and other modules are loaded. Who decides what should be 
loaded? What if I don't want to load a particular module e.g. IPv6.

If anybody could give me docs/info on how the OS loads/unloads modules 
on demand that will be much appreciated.

Thanks,
Vini
