Unlike as in the x86 world there's no common interface for querying
such information on sun4u machines but rather they are accessible via
model-specific (apparently Sun had no need to make the life of third
party developers easy with either their hardware or Solaris and
generally liked to re-invent the wheel) solutions if implemented at
all, which FreeBSD supports none so far. Partly this is due to the
amount of work involved to make this work and also partly due to the
fact that FreeBSD lacks an generic actuator- and sensors-framework
(one actually shouldn't need to re-implement access to sensors,
fan-control subroutines etc for every model) to build upon.
However, typically the ALOM, LOM, ILOM, RSC etc management cards also
allow easy access to such information via the `show environment` and
`showenvironment` commands respectively, I'm not sure E420R uses one
of these though.
