Bug Description
At first I thought this was just an issue with Ubuntu and Nouveau, but I noticed this happens with all distro's wich feature a kernel version higher than 2.6.35 (around that, I know it *does* occur in 2.6.39, but not in 2.6.35). My graphic card gets very hot. So does the rest of my laptop's components, but less so. In all of the distro's I've tested I must come to the conclusion it's a bug in the Linux kernel that started occuring around 2.6.36 or something like that. I've got aa graphic card capable of 3D compositing until Ubuntu 10.10, in 11.04 this didn't work anymore all of a sudden, same for all distro's based on Ubuntu.
The sensors indicate very high temperatures (and so do my hands and knees when holding the laptop or putting it on my knees) for any distro a kernel version higher than 2.6.35, and this became a lot worse with the 3.x series somewhere (Ubuntu 11.10 is the milestone for me). I've already heard there are more people than only me with this problem.
My laptop's a Dell Latitude D620, Intel Core 2 Duo 2GHz, 2GB RAM, NVidia Quadro NVS 110M (64MB video RAM).

Old report:
I was just trying out Ubuntu 11.10 from my USB drive. I used it for about 10 minutes, and then my laptop cooler started spinning a little louder (still not as loud as it normally does in 11.04). I installed lm-sensors, ran sensors-detect, en checked the output of the sensors command... Glad I was sitting in an armchair or I would have fallen off.

This seems to me like a critical bug, as this could kill users their hardware. My laptop was indeed getting quite hot on my knees (though I wouldn't have dreamed of 108°C!). I ran sensors again, just to be sure, all that happened was that the temperature had risen by anoter 1°C.
I'm just using Unity 2D, as my graphic card (NVidia Quadro NVS 110M) has been blacklisted for the normal Unity.
I wasn't doing anything in particular. Only playing some music using Banshee (by the way, the music lens doesn't show any songs in Unity 2D? Also, the font in the Unity 2D Panel changes after a few minutes use, as you can see in the screenshot).

Ubuntu 11.10 AMD64 Daily (25th of september, 2011), booted from a USB drive.
