Comment(by erikos):

 I adapted the patch from Martin and changed it to use /proc/net/tcp

      no)  ethtool -s $WLANIFACE wol d ;;
      esac
  }
 }}}

 This works fine, though there are some occasions where I am not sure why a
 machine wakes up. The powerd logs indicate only due to a wlan package. No
 activity was shared yet, only two machines (XO-1.5) around. Maybe a
 presence update. Will try to get some more info here.

 Another issue is that the XO-1 do not seem to idel-suspend anymore. I made
 sure that the file '/etc/powerd/flags/inhibit-suspend' is not there. I
 tried as well with powerd-26, to see if there was a regression, but on 353
 the XO-1 just don't want to idle suspend. I am quite sure it worked for me
 before. If someone has an idea what change that could have caused it...
