I have Lenovo Thinkpad R400 laptop. It has Intel Centrino Core 2 Duo processor with ATI Radeon 3400 series graphics card and Intel Mobility chipset series 4 Integrated graphics controller.
I have Squeeze ( stable) installed on it with kernel 2.6.32-5-686 .
My laptop gets very hot within 10 minutes whether I do any task or not. Also battery life is almost 40% as compared to Windows. I am more worried about temperature as it remains completely cool in windows.
Mostly CPU load remains around 10% and CPU spends 99.99% time at 800MHz clock. I believe heat generated is by graphics card chipset.
Following are some information about my machine

I also had radeon installed as directed on http://wiki.debian.org/ATIProprietary?highlight=((ATIProprietary)) .nitin@debian:~$ lsmod | grep i915

Following error is reported in dmesg:
I believe heat generated is probably by graphics chipsets. Normally I had both module i915 and radeon loaded in kernel. This was resulting in slow performance of machine. Once i removed radeon, performance did increased.nitin@debian:~$ dmesg | grep radeon

I cannot remove i915 to test how radeon performs. I need help on it as well.
I will like help on keeping temprature of my laptop low. I believe heat is generated by graphics chipset. I had tried to provide required information. I welcome all comments.
