Description of problem:
lm_sensors does not detect "Nuvoton NCT6791D Super IO Sensors" in the versions supplied by F19 and F20. Functionality for this chipset was added in lm_sensors 3.3.5. I just ran into this problem on my ASUS A88X-PRO mainboard, though it sounds like the chipset's present in more than just that one.
Version-Release number of selected component (if applicable):
F19's 3.3.3 doesn't have support (nor would F20's 3.3.4). lm_sensors 3.3.5 fixes the problem.
sensors-detect on a mainboard with an NCT6791D chip.
Steps to Reproduce:
Found unknown chip with ID 0xc803
(logical device B has address 0x290, could be sensors)
Found `Nuvoton NCT6791D Super IO Sensors' Success!
(address 0x290, driver `nct6775')

On Fedora 20 manually updating to lm_sensors-3.3.5-5 using the below RPM's resolves the NCT6791D not detecting, sensors now displays all the sensors from the motherboard and allows PWM fan control.

bugs or makes them obsolete.
Fedora 19 changed to end-of-life (EOL) status on 2015-01-06. Fedora 19 is
