I cannot open FATE#323189 on features.opensuse.org, but I made the changes you suggested to the files in my package. It worked for all _standard_ distributions I use (13.1, 13.2, 42.1, 42.2, 42.3), but the build for Tumbleweed is still waiting for the build of the latest Kernel:stable version to finish. Once that's done and it also works for Tumbleweed, I'll close this ticket. Thx for the hint!
