Two kmod packaging questions

Having got the wl-kmod package finished and submitted I've got a couple of questions about the release/build process: 1) Is there anything that I need to do when a new kernel is released into updates-testing or when that kernel is pushed into updates? I presume the kmod will need to be rebuilt against the newer kernel, but is this automated, or does someone else look after it? How do we ensure that our kmod gets into the rpmfusion repos as quickly as possible after the fedora team release new kernels? 2) When we release the kmod do we bother to release it also for older kernels or just for the most recent one? i.e. do we release a build that is for the stock F9 kernel that comes on the installation media? Thanks Chris
