Same here: no information via /proc/cpuinfo, but via something like
watch cat /sys/devices/temperatures/sensor{1,2}_temperature
$ cat /proc/cpuinfo

With this line in /etc/modules temperature *seems* being fine here:
therm_adt746x limit_adjust=-3
$ /sbin/modinfo therm_adt746x

srcversion: C5E974A566B0BBEE52DC46F
depends:
vermagic: 2.6.26-rc5-53c8ba9 mod_unload
parm: limit_adjust:Adjust maximum temperatures (50 sensor1, 70
sensor2) by N degrees. (int)
parm: fan_speed:Specify starting fan speed (0-255) (default 64) (int)
parm: verbose:Verbose log operations (default 0) (bool)
Although I'm not sure whether your G4 is an alubook or not ..
I look to the fan speed like so:
watch cat /sys/devices/temperatures/sensor1_fan_speed
This output (slightly edited for better readability) here:
$ dmesg | grep -i ADT746
[ ... ] adt746x: version 1 (supported)
[ ... ] adt746x: Thermostat bus: 0, address: 0x2e, limit_adjust: -3, fan_speed:
-1
[ ... ] adt746x: ADT7467 initializing
[ ... ] adt746x: Lowering max temperatures from 81, 80, 87 to 67, 47, 67
