This is similar to how RPM Fusion's kmod (binary packages) and akmod
("source" packages similar to the DKMS ones) setup works.

They must have done so, because RPM Fusion decided DKMS is not suitable for
binary packages and thus developed their own solution (akmod) which uses
the same specfiles for the akmod packages and the binary kmod packages.

But can't we just reuse the work from RPM Fusion or from Mandriva?
