I made some changes back in January correcting the type signs for temperature reading, because of that same problem. I still see some temperature warnings on my Aluminum PowerBook (127C), but I think that's a glitch in the sensor, not necessarily the driver, but I'm not certain. Any time I see all 1's in a reading, I'm suspicious of the reading itself, not of the environment, without other data. - Justin
