customized kernel for reducing laptop power consumption

Do there exist any custom kernels that reduce power consumption, possible even geared towards laptop (e.g. 2nd gen sandybridge) users?

For instance if one uses the stock kernel vs. linux-ck, etc... are there any drastic differences in power consumption, or are most of these custom kernels geared towards performance improvements?

actually no.

there is a patch you can apply related to aspm handling which might land up in 3.3, it should help a bit.

I know you were looking for a customized kernel that reduces power consumption but have you looked at https://wiki.archlinux.org/index.php/Laptop_Mode_Tools ?
