If you changed it to "/usr/src/linux-2.4.22-21mdk/", you should be OK on 
this score. The path is contains is *supposed* to be a symlink to the 
actual location of kernel source (probably created by "make 
modules_install" in the kernel Makefile, but that's really just a guess).

This sounds more and more like a naming problem. (In saying that, I'm 
assuming that all of the commands listed above reported no problems -- no 
errors or warnings -- except for the final modprobe error. I'm also 
assuming you were root when you did all of it.)

1. What is the actual name of the directory path to your modules for your 

2. Alternately, what is the name of the running kernel ("uname -a")?

3. What is the name of the kernel in your kernel-source file (this gets 
constructed from the 4 kernel-name variables near the top of the kernel 

If the answers to 2 and 3 don't contain the same name, then that is your 
problem. If they do, then ...

4. What does "find / -name ivtv.o" (run as root) return in the way of 
locations for copies of the module? If your procedure is not putting the 
module in the right place, where *is* it putting ivtv.o?
