Thats very interesting.

In my case I just experimented for you:

Without X -> avg.15900 mW
With    X -> avg.16300 mW

not very different I am afraid.

Should I mention that in the console where I have experimented I am 
using the 1400x1050 framebuffer ?

I am using Debian sid and therefore have Debian's X (4.3.0.dfsg.1-1).

The driver I declare in my XF86Config4 is ati but I guess it's a synonym 
for radeon.

You will shortly see my XF86Config in another thread since I am getting 
CRAZY to get an external projector working !!! :(

HTH,
