[lm-sensors] Kernel support for ITE8758E

[Virgil Gheorghiu]

Dear lm-sensors team,

We have a variety of Shuttle machines we run Linux on.
The newest addition, an SX58J3, differs from the older SX58H7 in several  
ways.
In sensors' case, the old board has an ITE8720F, whereas the new one has  
an ITE8758E, which neither Google nor www.alldatasheet.com has any  
knowledge of.
dmidecode(8) reports both boards to be "SX58 V10" (Base Board  
Information/Product Name/Version), yet differences do not stop at sensors  
chips.
I've included a small 'lspci -nn' difference between the two at the end of  
this message.

I did a simple 'add device ID' in several places in it87.c, and added  
support for it in sensors-detect.
Without a sensors.conf config file in place, it87.ko reports temperature  
values matching the BIOS.
Voltages are all over the place, and so is the single fan.
While making the fan value obey wasn't bad but I need serious  
investigation to match voltages reported by it87 to the BIOS.
Since the machine is about to be deployed, I cannot do this at this time.

One other problem I noticed is an SNMP bulkwalk to this machine returns:
snmpbulkwalk -v2c -c****** new-sk58j3 LM-SENSORS-MIB::lmFanSensorsTable
LM-SENSORS-MIB::lmFanSensorsTable = No Such Object available on this agent  
at this OID
What is the connection between a new it87.ko kernel module and  
libsensors.4.2.1 (libsensors4 1:3.1.2-2 lenny/sid), and what do I need to  
do to support it8758 at libsensors4's level so that snmpd picks it up?

I would like to share the above patches (subject to more informed people's  
scrutiny) and also the sensors.conf for all motherboards we use here.
There are undoubtedly some miskates :-) but we use them with a good degree  
of success in monitoring a variety of machines (sensors.cs.uchicago.edu is  
one such publicly open example).
Please let me know where can I send a bunch of configuration files,  
patches and pictures of the ITE8758E chip, and in what format (*.tar.bz2  
?).

Thank you for your help and for making lm-sensors possible,
