That's correct.
But even if intpm supported the chipset it's not guaranteed that the HWM
chip is exposed via SMBus.
I haven't used mbmon in a while, maybe there is a way to ask it to try
using a different address for LPC (ISA) IO access method.  The address
could be discovered using superiotool (from ports) and the chip's
documentation.
However, I am not confident that mbmon knows enough about that specific
chip (IT8728F).
