Rocko,
Tried it and there wasn't a great deal of difference overall on my Thinkpad X300

The Load balancing ticks dropped some but
were replaced by a new item called kworker/0:0 

Here is the result from powertop -d


Wakeups-from-idle per second : 226.3	interval: 15.0s
no ACPI power usage estimate available
Top causes for wakeups:
  20.0% ( 28.1)   kworker/0:0
  13.5% ( 19.0)   [kernel scheduler] Load balancing tick
  13.0% ( 18.3)   firefox-bin
  12.4% ( 17.4)   [extra timer interrupt]
   7.1% ( 10.0)   nautilus
   5.4% (  7.6)   [iwlagn] <interrupt>
   3.5% (  4.9)   syndaemon
   3.2% (  4.5)   [TLB shootdowns] <kernel IPI>
   3.2% (  4.5)   [kernel core] hrtimer_start (tick_sched_timer)
   2.9% (  4.1)   apt-check
   2.5% (  3.5)   [acpi] <interrupt>
   2.1% (  3.0)   Xorg
