NBo influence sorry.

Well I have _NO_ time for this until end of next week, but I was curious and tired from studying so I have looked :)

here are the results:

This software has an interesting file smbus.sys

HT1000 legacy southbridge should be same as:
0200	OSB4 South Bridge
0201	CSB5 South Bridge

let confirm by:
Please provide output of

lspci -v -v -v
and
lspci -n

Maybe just adding the line with:
        { PCI_DEVICE(0x1166, 0x205),
          .driver_data = 0 },

Will do the trick. Assuming you have the "HT1000 Legacy South Bridge" If not we must find out where is the PCI id located and start from that point.
