Chances are that is the power on CPU speed. We don't yet support CPU  
frequency scaling or enough of the power and thermal management to  
make it safe to kick the cpu up to full speed. There are patches that  
enable thermal and fan speed monitoring against current but I  
wouldn't expect them to make it into any of the release branches  
anytime soon.
