power regressions

hello, as remarked by phoronix.com, new kernel versions are introducing outstanding power consumption regressions. they point out some advices too http://www.phoronix.com/scan.php?page=article&item=intel_i915_power&a... what's the take of fedora on this? will it be upstream or distro specific? I've read the good fedora "Power Management Guide", it deserves more prominent place into fedora docs website. but, I have a question: "Additionally (or alternatively) you can perform many small adjustments to various system settings:" "enable laptop mode (part of the laptop-battery-powersave profile)" so, I've installed tuned, set laptop-battery-powersave profile, and I have to additionally pass these commands? or are they are already active, as I expect? hope some more upstream work on power consumption reduction will be placed in line for each release, specially in this era of ultramobility, ultrascalability, and environmental emergency. my eeepc with winxp was reaching 10 hours and half of autonomy and some 7 with lucid. now we are at 4 and an half.. anyway fedora 15 has been a great release kind regards, alex -- Caselle da 1GB, trasmetti allegati fino a 3GB e in piu' IMAP, POP3 e SMTP autenticato?
