Could you give to us some links about powersaving with EST? For now, i'm using 
powerd: 
powerd_enable="YES" 
powerd_flags="-a maximum -b adaptive -n adaptive -r 30 -i 35" 
in my rc.conf. I'm not on AMD64, so i'm sorry, powerd works well to me (125 MHz 
on battery and 2.16GHz on AC), BUT battery life time is equal in both cases and 
something about 50 minutes, so i think powerd is not so powerfull for me.
