> I have finally compiled a patched kernel myself and couldn't be happier with results. Not only battery life increased (~1 additional hour), but what's more important, performance on battery improved significantly.
(Note: I have not tried this myself yet...maybe this weekend)
Some other possibly useful links I just came across related to this patch:
Looking at the patch, it doesn't appear to tackle the sleep state coordination issues that mjg59 was talking about. Which doesn't mean that the impact of this patch on power savings isn't still nice to have. I figure it'll take them a while longer to get sleep states working as intended.
