Do you have figures to show that in practice ?  Last year when I 
received my T42 I spent about a month to tweak everything to reach to 
lowest power consumption, so I compared the open-source power management 
AND the closed-source one. At least with no use of Dri on the desktop, 
doing classic tasks, I did not notice any difference in power 
consumption. And by the way shame on ati for their closed source driver 
... I prefer the free one even with no DRI.
