To whom it may concern: I am an avid Linux user and recent BSD convert. I have a Lenovo Thinkpad L412 with an Intel i3 370M & ATI HD 5145(rebadged HD4570) graphics. I recently tried Fedora 14 and had the same problem that I have had with PC-BSD, the underside of the laptop got HOT! When I was running on the radeon driver it was ridiculously hot, then when i switched to the catalyst it was managable. I found out that the following link worked in Fedora 14: http://forums.fedoraforum.org/showthread.php?t=155503. In PC-BSD I was using the radeon driver with DynamicPM, Clockgating, and ForceLowPowerMode all on and it was still hot. After careful consideration and diagnosis, with thanks to Dru and Martin, we believe that this might be a dri problem on the kernel side, possibly linked to the Intel Core i3. I am willing to do testing for you on PC-BSD 8.2 if you would like to help everyone. Let me know what I can do to help! Thought I would list the repo link: http://download1.rpmfusion.org/nonfree/fedora/updates/testing/14/i386/repoview/index.html BEFORE SENDING FINISH THIS! pciconf -lv: hostb0@pci0:0:0:0: class=0x060000
