yes, this is true -  even booting under knoppix and loading some special drivers, u can pass -1 (or some special value) to the linux driver and it will let the fan spin lose...and it definitely goes far faster than the approximately 3.5K rpm it does with fan_level=7 and fan=0.

I have a Thinkpad Z60m, single core, 2 GHz. Everything original except the memory, increased to 1.5 GB.

in my case, i think the GPU heats up pretty badly... it is very hot where I think the video card is located.

I've posted to both mobile@ and acpi@ under the subject of 'Management of Thermal' with my woes while on the latest 6.2 before 7 went into Beta1. Since my upgrade to 7 i've had no major issues with heat. The emails i've posted previously show the settings i have been using, as well as whatever I had done in knoppix to manage the speed of the fan.
