Well, that's what fanX_div is meant for. As far as I know, the number of
pulse/rotation depends mostly on the fan itself, not on the monitoring
chipset. That's why we let the users change the fanX_div value through
the config file.
Maybe there's actually something to be fixed in the adm1026 driver, but
maybe this is just a matter of setting the right fanX_div for unregular
