Jean,

it87_write_value(data, IT87_REG_CONFIG,
                 (it87_read_value(data, IT87_REG_CONFIG) & 0x36)
			| (update_vbat ? 0x41 : 0x01));

Unless I am missing something, the above code enables interrupts by clearing
bit 3. In combination with having bit 1 set, this means that SMI# interrupts
will be enabled. Default value for the register, at least for IT8721F and
IT8718F, is 0x18. Replacing the 0x36 mask above with 0x3e might possibly solve
the problem.
