For what it's worth, my problems seemed to be due to the ATI chipset and
open source driver (not that the ATI one is better). With the same
distribution copied on a thinkpad W500 and using the intel chip instead
of the ATI one, I get a much better:

  36.0% ( 55.0)       <interrupt> : ahci, yenta, i915 at pci:0000:00:02.0 
  31.0% ( 47.3)     <kernel core> : hrtimer_start_range_ns (tick_sched_timer) 

and can actually get consumption down to 11W or so, which is amazing for
a big desktop replacement dual core duo with 1920x1200
