Yes, the chip supports and even has automatic fan speed control. The 2.4
driver has support for both. Takeru was working on adding support to the
2.6 driver but suddenly vanished. I hope he's OK...

Recently, Jonas Munsin started from Takeru's preliminary patch and
completed the work. You can see his patch here:

Hopefully this will be integrated into the main driver soon. Testing is

BTW I have fixed this horrible bug in CVS. Sensors-detect should now be
more clever and see that this is the same driver for the same chip and
display only one. Care to test?
