Pali, I know this isn't ideal, but at this point I recommend you stop fighting with the repository and instead upload new kernel-power versions with a different internal package name. I.E. "kernel-power2-[whatever]" instead of "kernel-power-[whatever]".

Yeah it's an ugly work around and I know we both personally dislike those, but it's better to be able to promote your packages correctly and not have to deal with them getting stuck 'invisible' to the package interface or whatever. Starting with a new package name should get you a proper fresh start - or, at the worst, indicate that the problem is with your package somewhere, though I doubt that's the case.
