hello list.

im new here, but have found many useful thing on the archives and the
thinkwiki wiki in the past.=20

I have one question which i did not manage to find an answer to;
if i use ATI's propriety drivers for the bundled FireGL V3200, i can
control the power level of the card. this can squeeze almost 45 to 60
minutes of juice from my battery. However, im not very inclined to using
the closed sourced driver.
So, i was wondering, does anyone know of a way to control the power
levels of the graphics card without using this driver?=20
even a direction to get me going will be nice, as i have no idea where
to start:
i guess this is done in the binary section of the driver (not even sure
if the kernel blob or the X blob) by setting some hardware registers. I
did not managed to find where as of yet.

if someone have succeeded (or even tried) i would appreciate the info.
thanks.
