Ah - I looked at the LM manuals, as I had the references handy, and
assumed the others were similar. They are almost different enough to
have separate drivers. However, I think that it makes sense to add
the changes in the patch to our driver.

Looks like wbsio handles the attachment glue (rather than lm at iic).

That seems fairly standard. If the firmware can display the sensor
values, it's possible to do some correlation, but otherwise I haven't
found a good way, especially with the range of temperatures and voltage
sources that can be measured.
As an example where the firmware can show the values, I can translate
sensors on a Sun fire V240:
[adm1026hm0]
F0.RS: 5720 RPM
...
MB.P0.T_CORE: 47.000 degC
...
MB.V_GBE_+2V5: 2.508 V
...
[lmtemp0]
MB.T_ENC: 11.000 degC
which is nice.
Regards,
J
PS. Approximate translations:
F0.RS fan 0 rotational speed
MB.P0.T_CORE main board processor 0 temperature (core)
MB.V_GBE_+2V5 main board gigabit ethernet +2.5V
MB.T_ENC main board temperature (enclosure)
