Linux kernel 3.3 power regression

I am using Fedora 16 in my DELL n4110. I recently upgraded the kernel from 3.2 to 3.3. In contradiction to the official claim, my system still drains battery as hell. It only provides 1:30 to 2 hrs of backup under normal stress as before, where as Windows provides 3hrs/+ of backup under similar stress.

Below are some screen shots from powertop, stats on the services running in my box and few lines from grub.cfg.

Is this normal? Are there still problems with power consumption in 3.3?

Is there any way to report this problem to the official kernel group???
