After packaging powertop (actually shamelessly stealing .spec and patches from fedora 18), i get this:

Failed to mount debugfs!
exiting...

Looking in the README included in the 2.4 tarball, i do not see debugfs on the list of requirement. Is there a place where we can read the complete list of requirements?
