Could you try this experimental patch?

Hi,

on top of kernel 3.9.4 (with TuxOnIce patch), iwconfig wlan0 power on
now saves more than 1 W on my ThinkPad X61s with iwl4965. I can finally
switch to a recent kernel. Thanks a lot.

This patch stuck on mailing list far too long, I'll post it. Even if it
crash firmware on 3945, power save is disabled by default.
