Usually the ACPI code tries to read the speed from the sensor a few times until it "makes sense" (according to some board specific logic); if it fails it returns garbage. If you send me the DSDT (/sys/firmware/acpi/tables/DSDT) I'll take a look. In theory you could rewrite the method and replace the DSDT, but I don't think it's worth the effort.
