Hi,
I do not know, but that reminds me something I wonder :
Does the radeonfb driver handle powerconsumption management facilities 
in ati recent cards ?
Like ati/X handles it throught DynamicClock for exemple.
Actually I work a lot in emacs without X but I can not notice a big 
difference in the power consumption,
while the load on the GPU should be much lower.

Does someone know something about that ?

Thanks
