This pretty much rules out the theory of a second hardware monitoring
device to which the last fan would be connected.

I took a look at the datasheet for this chip and could not find
anything wrong with the driver.

However, if you provide a few register dumps, I can double check if the
chip is in an unexpected state.

# rmmod it87
# isadump -k 0x87,0x01,0x55,0x55 0x2e 0x2f 0x07
# isadump 0x295 0x296
# modprobe it87

With these two register dumps I should be able to check if fan4_input
is supposed to be enabled or disabled.
