@florinn: Please close all applications (especially firefox and thunderbird) before posting such measurements. In your case, firefox is probably running some heavy animations or executing some scripts with many timeouts. It is not the kernel's fault that the user-space is generating useless wakeups.
On my laptop, with kernel 2.6.37, I easily get under 20 wakeups/second.
