how to package a kernel module?

[Christoph Mathys]

Hello!

Not sure if I picked to correct list for asking about packaging kernel 
modules and handle different kernels, so sorry if this question is OT.

The software in question contains some userland tools and a kernel 
module. It seems pretty straight forward to just compile and pack 
everything together for the system as it is just at the given moment.

However, I'm completely lost when it comes to handling kernel modules in 
a little more elaborate way. I could not find much documenation about 
how to do this, module-assistant being more or less the only specific 
tool for module handling I found.

So, how do I handle different flavours and versions of a kernel? What to 
do if the kernel is upgraded? Do I need to provide a package for every 
kernel that should be supported? Or better create a package which will 
compile itself if the kernel on the system is not supported? But then, 
what to do if a different kernel is booted next time? I hope for some 
pointers on how I could handle this one or which packages do a similar 
thing so I could take a closer look.

Thanks!
Christoph
