Eelco Dolstra 8f4d8cf620 Enable the power management module by default 
After all, we don't want NixOS machines to contribute to global
warming more than necessary!

Eelco Dolstra c6d12257f1 systemd: Run the powerManagement.* hooks on suspend/resume 
Also, drop pm-utils. Systemd now takes care of suspend/resume.

Eelco Dolstra 573877c1ac * Use boot.kernelModules everywhere instead of explicit calls to 
modprobe.
* Move the implementation of boot.kernelModules from the udev job to
  the activation script.  This prevents races with the udev job.
* Drop references to the "capability" kernel module, which no longer
  exists.

Eelco Dolstra cc41bce79d * Prevent merging of some options. P.S. maybe string options 
should be "uniq" by default.

Eelco Dolstra cf36b3db80 * If power management is enabled, set the governor to ‘ondemand’ by 
default.  See
  
    http://www.codon.org.uk/~mjg59/power/good_practices.html
    
  for the reasoning.  (Basically, the ‘performance’ and ‘powersave’
  governors don't actually provide extra performance or power savings
  in most cases.)

  It used to be that desktop environments like KDE were able to set
  the governor through HAL (e.g. KDE could be configured to switch to
  the powersave governor when the user unplugs his laptop).  However,
  this is no longer the case with upower — it is now expected that
  everybody uses the ondemand governor.  See

    http://old.nabble.com/-PATCH--powerdevil-remove-cpufreq.patch-td27815354.html

* Rename ‘cpuFreqGovernor’ to ‘powerManagement.cpuFreqGovernor’.

* Include cpufreq-utils in the system path if a governor is set, since
  we depend on it anyway.

Eelco Dolstra cddc67a653 * Try to load the p4_clockmod kernel module, which provides 
CPU frequency scaling on some Intel CPUs.

Eelco Dolstra 86d53a5b8b * Load the cpufreq modules, since these are not loaded automatically 
by udev.  The kernel can load governors on demand, but if they are
  not loaded, HAL doesn't know about them and they don't show up in
  the KDE System Settings.

Eelco Dolstra 9174b4ab42 * Provide a convience option for commands that must be executed both 
when the system boots and when it resumes from suspend.

Eelco Dolstra 1affc9168e * Move power management configuration into a separate module from 
the acpid service.
* Add a pm-utils hook to allow commands to be executed when the system
  suspends/resumes etc.
