Driver porting: compiling external modules

This is probably a dumb question, but what is the module that you insmod? When I compile the hello_world I get a hello_world.o and a hello_world.ko. Both of these can be insmod'ed but the hello_world.o give an error "no version magic, tainting kernel" -- so I assume the hello_world.ko is the one I want to use?

Driver porting: compiling external modules

It seems that this 2.5 method of compiling external modules does not work on older kernel versions. I tried the example .c and Makefile, and got the following results:- RedHat 7.3 out of the box (2.4.18-3 w/.config or any .o files). Compilation fails, thinking that module support is not compiled in.
- Version 2.4.20 I built and installed. Compilation failed, *** No rule to make target `modules'. This happens when make changed back to my working directory and did a make xxx modules. The kernel source base Makefile appears to be different in the 2.5.x versions.
So, will external modules require that the source be present, built and running? I don't believe any RedHat distributions will work.
What about the 2.4 or 2.2 target modules issue?
