My IBM Thinkpad R50p is affected as well. I was running SuSe and FC4 before and had no problems with shutdowns due to high temperatures. I do not remember, which kernel version I used, but I installed the kernel sources from 2.6.17 (with ubuntu patches) and recognized, that the ibm_acpi.c driver is outdated (compared to the driver in 2.6.20.1)
