This sounds like perhaps you need to add a patch tied to your southbridge. Generally the SMBus interface hangs off the southbridge or a power management controller. But you haven't told us which one, so any advice we may be able to give you is largely academic. Do you know the PCI ID of the *function* that implements the SMBus interface in your system? If so, grep through the kernel source and find which driver is attached to it, if any. If not, pciconf -lv is a good place to start. BMS
