"some chip" doesn't tell us much... Can you please provide the complete
output of "sensors"?

What is the exact motherboard model?

Any message in the kernel logs when you modprobe w83627hf? Does the
modprobe itself fail or succeed? If it fails, what's the error message?

What kernel is your gentoo system running?

Please compare /proc/ioports between a system where the w83627hf driver
works for you and a system where it doesn't. I'd suspect a resource
conflict.
