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
sensors:
radeon-pci-0200 Adapter: PCI adapter temp1: +82.0 C
On fglrx everything works fine.
