+The driver was then ported to

+.Sh CAVEATS
+Some vendors connect these chips to non-standard thermal diodes and
+resistors.
+This will result in bogus sensor values.
+.Sh BUGS
+Interrupt support is unimplemented.
+.Pp
+There are currently no known pnpbios IDs assigned to LM chips.
+.Pp
+This driver attaches to the Winbond W83791SD chip even though that
+chip does not have any sensors.
