ATI X1400 and PowerState

[moke1809 <moke1809@yahoo.de>]

Hi,

I'm running Lenny on a Thinkpad T60 with ATI X1400 GPU. Kernel is 
2.6.18-4 from testing, fglrx driver is 8.36.5-1 from experimental, xorg 
is 7.1.0-18 from testing.
I can set PowerPlay state of the card manually by using the
aticonfig --set-powerstate=NUMBER
but if I put the
Option "PowerState" "NUMBER"

in my xorg.conf, I get

fglrx(0): Option "PowerState" is not used.

Any idea how to get this working?
I tried putting the
aticonfig --set-powerstate=NUMBER
in my Fluxbox startup file, but that doesn't work either!

Regards
