It is as simple as:

* UNZIP the content of the archive into a directory named PowerPack that you create in your MyDocs/ folder (which is the one you see when you connect phone to PC).
* with a terminal place yourself in the folder (cd /home/user/MyDocs/PowerPack/)
* execute the command /usr/sbin/incepte *.deb and follow instructions (enter root password)

I must say the log file is *impressive* and so far so good with FasterN9 installed, everything seems indeed smoother. I did not find the LED notification setting yet, but overall this is GREAT news !
I hope with that to be able to use multiple mail account with push capabilities (today if you use more than one, you get high-idle current leakage...)
