Thanks for the proposal. Basically we want to know what hardware
monitoring chips are used in the system, and how they are wired. I
suspect that HP uses a non-standard I2C bus, possibly GPIO-driven.

Thomas, I've thought a bit more about your problem, and I'm now almost
certain that you won't find anything attached to your motherboard's
SMBus, even if you upgrade the BIOS or force the SMBus base address.
You said that the "hplog" utility was printing temperature values, so
it must get them from somewhere, and it definitely can't get them from
anything connected to the currently disabled SMBus. So there has to be
another, non-standard I2C bus somewhere on the board.
