I am _very_ inconclusive. I booted up on 2.6.30.1 on my thinkpad t61. the initial temperature dangled around 47 to 49.
The fan (output of cat /proc/acpi/ibm/fan) shows rpm of 2900. then I ran the CPU stress : stress --cpu 16 --vm 2 --vm-bytes 128M During the stress the fan as the output of the above remained at 2900(+/- 100) itself. and temperatures (from acpi -V) rose to upto 73 before I killed the stress call. After killing the fan stayed at around ~ 2900, but the temperatures rreturned to ~49 pretty soon. I am not sure why the bloody acpi is NOT controlling the fan speed when the CPU temperature is increasing. I tried listening in on the cpu to see if the fan speed is increasing but cudnt tell any difference. If someone could interpret these results it would be great.
