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.
