There's something you can download to change it at the click of a button, but I can't remember what it's called. >_< Sorry.
Do you mean acpi-cpufreq?

If you recompile your linux kernel, you could force it to remain idle and downclocked, but it would load very slowly. There's something you can download to change it at the click of a button, but I can't remember what it's called. >_< Sorry.
Sapphire 6850 100315L 250Mh/s @ 930 / 830 BFI_INT VECTORS AGGRESSION=13 -k phatk -v FASTLOOP=false For some odd reason memory clock will not go more than 100 Mhz less than core clock, if set lower it defaults to stock 1000Mhz memory clock
Sapphire 6950 2gb Dirt 3 340 Mh/z 850 / 725 BFI_INT VECTORS AGGRESSION=7 -k phatk DEVICE=0 -v FASTLOOP This card only allows the memory to be downclocked to a difference of -125Mhz or it defaults to stock mem clocks(1250Mhz)

I'd fix that memory clock if I were you. I'm running LinuxCoin on 5850's and have no problems downclocking memory. Be sure to set all 3 low/mid/high power levels to 300 memclock. If you post the .ovdr you're using maybe we could diagnose.
My whole rig(Phenom 965 + 2GPU's) Pulls 470w from wall when mining, when idle I am at 160w. I just wish Linux coin had a CPU down clock utility like PhenomMSRtweaker so I could force my AMD CPU in the most idle p-state and save some more electricity.
By the way, anyone know of a good linux AMD CPU control utility like PhenomMSRtweaker?

How many watts do you save with CPU downclocking? Never considered it myself.
Howdy, I just got my linuxcoin distro all set up on a hard drive install and have finally figured out how to OC my two GPU's in linux. I posted the instructions on linux coin wiki. If I wasn't a newb on this board I would post it on the linuxcoin forum post, but I'll need a couple more post before I can get there.
I really have to add, Linuxcoin rocks! I put an Ubuntu 11.04 distro up and get it all set up to compare thinking the results would be the same. Linux coin pulled 20-30 Mh/s per card more than Ubuntu did, this is using exactly the same clock and phoenix client.
I am a complete Linux newbie and I was able to figure it out.
Here is what I get from my two cards
