* If you want to activate realtime capabilities in the kernel,
  remove the line (if present):

    capability

  and add the line:
 
    realtime
  
  in the file /etc/modprobe.preload and adjust the realtime module
  options in /etc/modprobe.conf by adding:

     options realtime any=<0|1> mlock=<0|1> gid=<num>



  any: grant realtime privileges to any process (0=disabled, 1=enabled).
  gid: the group ID with access to realtime privileges (group ID).
  mlock: enable memory locking privileges (0=disabled, 1=enabled).

* For software suspend2 support you need to install the "hibernate" 
  package.
