In that case, you need some kind of per-distro cruft to make sure the module gets loaded at every boot, or a setuid program that can install the module, right?. Neither of these approaches works well in a cluster environment where you're running your tools from a shared directory.
I'd really like the default mode of operation for users to not require root privileges to get at normal functionality. This is something perfctr makes possible, for example.
