Kevin was kind enough to elaborate, hopefully his explanation is better than mine, and will help you understand the problem better. Meanwhile, to address Gustau's original point, the modules related to getting zfs up and running would still have to be loaded in loader.conf. My solution is only effective for those modules which are not related to getting the local disks on line (which fortunately is the vast majority of them).
