On opensource drivers power managment dont work at all on my Sapphire HD 2600 XT. I tried every state - nothing happens, even dynpm doesnt works. Tested on Ubuntu 11.04 amd64 and gentoo amd64-2.6.38. /sys/kernel/debug/dri/0/radeon_pm_info always same:
default engine clock: 800000 kHz
current engine clock: 796500 kHz
default memory clock: 700000 kHz
current memory clock: 693000 kHz
voltage: 1200 mV
PCIE lanes: 16
Adapter: PCI adapter
temp1: +82.0 C
On fglrx everything works fine.

Please attach a copy of your vbios rom.
(use lspci to get the bus id)
cd /sys/bus/pci/devices/<pci bus id>
echo 1 > rom
cat rom > /tmp/vbios.rom
echo 0 > rom

Any guess? May be vbios doesn`t have correct states information? Or may be its my fault and i don`t set some kernel options?
The vbios has the same clocks for every power mode.
It`s sad :( I hope you have any plans to advanced power management system to avoid exceptions like this. May be someone can edit this page http://www.x.org/wiki/RadeonFeature about wrong bios information to help another people with same issue. Anyway, thanks for the help.
Hello, how about making some handler to exceptions of the rules? I know there many wrong state info in video cards vbios. As i know we will not see kosher power management for a long time, so this may be not so bad solution for users at the moment. What developers think about this?
Sorry for my English, i hope you understand what i mean.
radeon has got some new power management infrastructure: http://www.botchco.com/agd5f/?p=57
