I think we can revert the hack, because the three-digit version number
will stay for foreseeable future and depmod is not the only tool that
used to rely on this. However, what you describe looks like a bug in
kmod's depmod. -b sets the basedir, depmod should not prepend it with
any compiled-in string.
