You just need to replace the affected binaries, if kernel version and all configuration stays the same. Of course it would be better to make a proper package. You may package out-of-tree modules separately, but you need a full kernel package for in-tree modules. Have a look at the PKGBUILDs in the repositories. There are examples for both. KR
