I've talked to khali (lm-sensors developer) on #linux-sensors and he confirmed that some chips show this behavior, i.e. they respond on _both_ the 0x2e and 0x4e config port. So this is likely neither a bug in superiotool nor in sensors-detect. I would argue that it's rather a bug in the chip; it makes it a lot harder to detect whether there are _two_ Superio I/Os on a board... lm-sensors has no problem with this, it stops scanning for chips as soon as it found one (so it talks to the IT8705F on 0x2e, I assume). For LinuxBIOS we can probably do the same if there's only one chip. I have no idea how we should handle the case where there are _really_ two IT8705F chips on the same board (but on different config ports). We probably cannot probe for this, so we'll have to hardcode it... Anyway, added link to the IT8705F dump in the wiki, thanks!
