    Interesting that minimal power draw with all options disabled is about 13 watts while it was 19 watts when 3.1 regression spotted. (vs about 14 watts in 3.0)
    So no more additional power regressions in 3.1?

    now using i915.i915_enable_rc6=1 for about a day on my asus u41sv without any hangs, power consumption down to 2.6.39 level

    Awesome article, just a minor nitpick:
    These options can be added to ... the grub.cfg file to be made permanent ...
    Uhh, no. The next kernel upgrade or anything that triggers update-grub will wipe it. Put the options into the /etc/default/grub file:
    Code:
    GRUB_CMDLINE_LINUX_DEFAULT="<put options here> quiet splash"
    Don't forget to then run update-grub.

    Some of these features, e.g. the LVDS downclocking has been in several generations of hardware. So it is worth trying it.
    Posting your findings would be useful.

    Wow, very interesting article.
    Need to try some of these tweaks on my Sandy Bridge notebook.

    I'm not quite sure what intel chips are affected by these settings. Is my 965 intel core2duo thinkpad affected?
