Hi Ok, this is the w83781d driver updated for 2.5.66bk2. It works over here. I did look at the changes needed for sysfs, but this beast have about 6 ctl_tables, and is hairy in general. I am not sure what is the best way to do it for the different chips, so here is what I have until I or somebody else can do the sysfs stuff.
