Power consumption comparing Ubuntu releases.

Hi again,

Continuing the blueprint work on analysing power consumption I've now 
run a bunch of tests across 6 different releases (Hardy LTS, Lucid LTS, 
Maverick, Natty, Oneiric and Precise LTS) and measured power consumption 
as well as wakeup events to try to identify trends and possible power 
sucking culprits.

There are two Libre Office spreadsheets available:

http://zinc.canonical.com/~cking/power-benchmarking/releases-comparisons/events-across-releases.ods

and a brief analysis write-up here:

This is useful for discussion, I'm not necessarily going to fix any 
issues found (and please don't shoot the messenger!) but I appreciate 
any feedback and questions.   I will be following this up with some more 
analysis on the cost of different desktops with different desktop 
applications later on this week.

Colin
