modules.cgz only has the modules object files. For upgrading, only
replacing the file is needed. Be sure to keep the structure, though

Only if new PCI IDs are supported by the driver do you need to update
the other module* files:

Add (if not exists) to module-info:
    "Some info"
Add (if not exists) to modules.dep:
<driver>: <dependencies>

<dependencies> can be found with: modinfo <driver> | grep depends

For modules.pcimap, add the new module to an existing
lib/modules/<version>, run depmod -a <version>, and update the entries
in modules.pcimap for the module with the ones in the new

I think that should be enough.
