Googling "excessive wakeups" shows lots of people have the problem for all kinds of software. Eg, these logs show the problem happening for Dropbox, Google Earth, Contacts, iPhoto, etc. These apps are used by millions of people, so I expect the problem is something outside of the software, like something in your OS configuration and hardware. Someone in that thread mentioned you might need more RAM or should uninstall junk anti virus software. Could that be the cause?
