Just recompiled my kernel with the ds1775 sensor for my MDD, and
noticed the sensor name sysctl is blank (shows up as 'dev.ds1775.0.',
no sensor name), because there is no hwsensor-location property for
the MDD sensor. Attached is a patch that adds a generic 'cpu' name.
Feel free to adjust it as you see fit (checking OF_getprop return
instead, etc).
