First, if your kernel module is controlling some hardware, then you
can copy your module to "/lib/modules/`uname -r`/drivers" directory
and then issue the "/sbin/depmode -a" command. Your module will be
registered in your system. Then when say PCI subsystem will find new
device which is not yet controlled by any driver it will load your
module.
The other way is to use the init script which is being executed on system boot.
This is for automatic insertion of the module. But for automatic device node
creation 'udev' is needed; am I right here?
