power consumption increased with kernel 3.2.5

The new kernel 3.2.5 supposedly fixed the old power regression introduced in 2.6.39 (or so). On my T60 laptop (Core 2 Duo) not only that the power consumption stayed high, but the pcie_aspm=force option passed to the kernel is not working anymore. The result: my laptop consumes 20W on idle (I use KDE, kmail and firefox on with 2 tabs open). That's 25% more than what I had with the older 3.2.4 kernel and pcie_aspm=force enabled.

powertop2 does not show  anything unusual, the CPU is basically idle on the lowest available frequency 98% of the time (I'm using the ondemand governor).

Did you guys experience something similar or is it just me?
