The way Linux does it is quite simple.  When a module is loaded some piece
of kernel memory is allocated, the module code is put there and and
relocated while resolving symbol references against the list of exported
kernel symbols.  Then the module init function is called which registers
itself with the kernel.  This is very much similar to the way dynamic
linking was done on old BSD systems.  The modules are just ordinary object
files, except that they must contain some special symbols for maintaining
the necessary information that is needed by insmod.
