Comment # 4 on bug 1158704 from Thomas Renninger

This should be handled by these lines in *.spec file.

%package -n ucode-amd
# new style (after 3.12 kernel somewhen)
Supplements:    modalias(cpu:type%%3Ax86*ven0002*)
# old style (before 3.16 kernel)
Supplements:   
modalias(x86cpu:vendor%%3A0002%%3Afamily%%3A*%%3Amodel%%3A*%%3Afeature%%3A*)

in obs (build.opensuse.org):
Kernel:HEAD/kernel-firmware kernel-firmware.spec

I do not have time to look at this right now, higher prio things have to be
