You know, pali, you can just package your kernel with the same package name as the power kernel - that's what lxp did when packaging power 46wl1, and so dpkg and apt-get see it as just another higher version of the power-kernel package, so there's none of this fiddling with either installing power kernel than your over it kernel, to get the dependencies right, or repackaging kernel power settings to not depend on kernel power.
