: Rafał,
That's what I needed to know. I'm am not familiar with 'git' and the
git checkout -t -b downclocking origin/master git am ~/archlinux/radeonhd/patches/*patch
parts were the parts I knew nothing about. I'll pull the patches, apply and report back. Something really has to give here. The heat is unbearable. To get the actual temp data, I have a digital multimeter with a great surface temperature probe on it ( Craftsman Model No. 82400 ) and I took the temperature readings on the left palm rest and left fan discharge of my laptop with the radeonhd driver active. The results:
Left Palm Rest Temp: 96 Deg. F
Left Fan Discharge: 147 Deg. F
The inside of this box is cooking.... That's with:
Option "ForceLowPowerMode" Option "LowPowerModeEngineClock" "140000"
I'll keep my fingers crossed and report back.
Nice, tests with your multimeter would be absolutely great. You may also try to reduce EngineClock later. For example change it from 140000 to 120000. If it doesn't cause any corruptions you can still try decreasing that. Don't worry about values you may use 139999, 139998, 139997, end so on.AtomBIOS will round it to something acceptable.

Uh oh,
I have some good news and I have some bad news. I did some additional testing with compiz and on cube rotate, I can't view the cube-caps any longer (the cube keeps jumping around) and when trying to rotate the cube, it will not rotate all the way around. It gets roughly 1/2 - 3/4 way around and then stops and you are left on desktop 3 or 4. Strange, I haven't seen that with the radeonhd driver before.
For testing purposes, I backed out the downclocking by setting: #if 0 in src/rhd_pm.c and compiz returned to normal. I don't know why it makes a difference, but it makes a real difference to the cube rotate function. Just one more challenge for the driver team ;-) Thanks again Rafał. -- David C. Rankin, J.D.,P.E.
