Lessons 1-99:
Get your modules included in the kernel.

None, the Linux development model is based on the fact that such changes 
are considered perfectly OK as long as all in-kernel users are being 
fixed.

The solution for your problem is that the authors of the modules you

they'll be automatically fixed when someone changes an in-kernel API.
