This worries me.  On my (very recent) powerbook G4 the therm_adt746x module
does not work.  I get the following error message during boot:

    adt746x: Thermostat bus: 0, address: 0x2e, limit_adjust: 0, fan_speed: -1
    Found KeyWest i2c on "uni-n", 2 channels, stepping: 4 bits
    Found KeyWest i2c on "mac-io", 1 channel, stepping: 4 bits
    adt746x: Thermostat failed to read config from bus 0 !

Reading /sys/devices/temperatures via cat results in a kernel oops
followed by a segfault of cat.

Am I in danger of destroying my hardware in this situation?

All the best,
