Hi,
I would like to know what is the state of the radeon-pilote power-management avancements with the kernel 2.6.34.
I search to improve my thermal management of my HD3650 ATI card. Not long ago I experimented different way to resolve my problem :
In a first time, I tested my config without KMS and tried with dynamicPM and clockgating option in xorg.conf => No results. I also tried with forcepowerlow, it was worse I loose 2D/3D performance without results on temperature.
So I tried with KMS and the next configuration ;
(In /boot/grub/menu.lst)
# (0) Arch Linux
title Arch Linux
root (hd0,6)
kernel /boot/vmlinuz26 root=/dev/disk/by-uuid/[...] ro radeon.pm=1 radeon.dynclks=1 radeon.dynpm=1
initrd /boot/kernel26.img
Thanks to it I had in the boot messages:
( dmesg | grep - i drm )
$ dmesg | grep -i drm
[drm] Initialized drm 1.1.0 20060810
[drm] radeon defaulting to kernel modesetting.
[drm] radeon kernel modesetting enabled.
[drm] initializing kernel modesetting (RV635 0x1002:0x9591).
.......
[drm] radeon: power management initialized
[drm] Detected VRAM RAM=256M, BAR=256M
[drm] RAM width 128bits DDR
......
But in fact it changed nothing. So my question is simple :
Currently, Is there a enabled radeon power-management with the 2.6.34 kernel ?
For the moment I use catalyst 10.7 driver, and I have the power-management activated, but the free radeon driver has better 2D performances.
Thanks, if someone would like to tell me the facts.

I've a poor English skills, please not write in SMS style, even I like Arch and I still make efforts to understand.
