Mandrake has the correct lm_sensors version in - however - the sensors_detect perl-script needs to be updated to find the correct chip. You can get that script here:
http://www2.lm-sensors.nu/~lm78/cvs/lm_sensors2/prog/detect/sensors-detect
A local copy is attached to this FAQ entry.
Once run - you need to make sure that the following modules are loaded through /etc/sysconfig/lm_sensors

MODULE_0=i2c-viapro
MODULE_1=i2c-isa
MODULE_2=eeprom
MODULE_3=vt1211

After that - adapt the /etc/sensors.conf file - Check mine in the related files section of this FAQ. Note that the Mini-ITC Nemiah M10000 seem to have only one temperature sensor. All others give back Junk.
Check the entire setup by starting it through /etc/rc.d/init.d/lm_sensors start After that - a sensors output should provide something like this:
