Bug Description
Binary package hint: xserver-
With my hardware - Mobility Radeon 3400 (RV620) - I have no power management with the opensource drivers, both ati and radeonhd. The system fans keep spining at high speed constantly even when the temperatures (cores and CPU) are very low.
Using fglrx I have power management. The fans increase and decrease speed as needed by the system.
Please contact me for more info if needed.

This may not immediately help, but the upstream radeon driver already has some new power management features that aren't included in Jaunty. There are new xorg.conf options ClockGating, ForceLowPowerMode and DynamicPM. www.phoronix. com/scan. php?page= news_item& px=NzIwNg www.botchco. com/agd5f/ ?page_id= 2

IMO the clocks don't go down far enough by default though, only to half of my cards 750MHz, whereas fglrx goes down to 165MHz and the card can still handle 80MHz. When I patched the source for lower clocks it came within 3W of the power draw with fglrx.
Some numbers from my HD4670 in a desktop system xorg-video- radeon 1:6.12.1-0ubuntu2, 750/873
93W with Jaunty xserver-
83W with upstream radeon, ClockGating and ForceLowPowerMode, 375/435?
77W with upstream radeon, ClockGating and patched clocks, 165/250
74W with Jaunty fglrx, 165/250 (engine/memory)
