Heavy increase in idle power between 2.6.22 and .24

[Dietz Proepper]

Hi,

yesterday I noticed a strange behaviour regarding the 2.6.24 kernel: The 
idle power consumption went up to around 21 W, while it was around 16.5W 
with a 2.6.22 kernel with ahaci powersave patch applied. The kernel 
configuration stayed untouched.

The machine is a Lenovo Z61 m.

Any idea?
