 The driver only updates its values each 1.5 seconds; reading it more often
 will do no harm, but will return 'old' values.

+This driver handles sensors integrated in some VIA south bridges. It is
+possible that a motherboard maker used a VT82C686A/B chip as part of a
+product design but was not interested in its hardware monitoring features,
+in which case the sensor inputs will not be wired. This is the case of
+the Asus K7V, A7V and A7V133 motherboards, to name only a few of them.
+So, if you need the force_addr parameter, and end up with values which
+don't seem to make any sense, don't look any further: your chip is simply
+not wired for hardware monitoring.
