I also bought an EE part (3800+ EE).  I really want to get to the point
where I can feel good about leaving the frontend running all the time.  My
family doesn't like to wait 2 minutes for bootup to watch TV.  And since
Ubuntu suspend doesn't work, I want to get the power down.  Right now,
with a middle of the road PSU I have it at 49W at idle.  I think if I
update it to a PicoPSU and a dell 12V brick, I can get that down to 45W. 
Doing this will get rid of the PSU fan noise which for this system is
loud.

I have managed to downvolt and downclock to get the 49W.  I would like to
tweak the powernow-k8 to drop the core voltage from the idle 1.0v level to
0.8v and the frequency down as well.  Ideally, I'd like to see something
around 35W idle.  This is what the via system I was testing consumed.  A
stretch I know.  I'd like to have lm_sensors working so I can confirm the
voltages for powernow-k8 instead of probing the motherboard with a meter.
