I'm trying to get the CPU temperature using lm_sensors.

it8712-isa-0290

eeprom-i2c-0-52
Adapter: SMBus I801 adapter at 1400
Memory type: DDR SDRAM DIMM
Memory size (MB): 512

I compiled all the modules in the kernel related to sensors, as I didn't know which ones to use. I did run sesnors-detect:
| Quote: | # sensors-detect
This program will help you determine which I2C/SMBus modules you need to
load to use lm_sensors most effectively. You need to have i2c and
lm_sensors installed before running this program.
Also, you need to be `root', or at least have access to the /dev/i2c-*
files, for most things.
If you have patched your kernel and have some drivers built in, you can
safely answer NO if asked to load some modules. In this case, things may
seem a bit confusing, but they will still work.
It is generally safe and recommended to accept the default answers to all
questions, unless you know what you're doing.
We can start with probing for (PCI) I2C or SMBus adapters.
You do not need any special privileges for this.
Do you want to probe now? (YES/no):
Probing for PCI bus adapters...
Use driver `i2c-i801' for device 00:1f.3: Intel 82801EB ICH5
Probe succesfully concluded.
We will now try to load each adapter module in turn.
Module `i2c-i801' already loaded.
If you have undetectable or unsupported adapters, you can have them
scanned by manually loading the modules before running this script.
To continue, we need module `i2c-dev' to be loaded.
If it is built-in into your kernel, you can safely skip this.
i2c-dev is already loaded.
We are now going to do the adapter probings. Some adapters may hang halfway
through; we can't really help that. Also, some chips will be double detected;
we choose the one with the highest confidence value in that case.
If you found that the adapter hung after probing a certain address, you can
specify that address to remain unprobed. That often
includes address 0x69 (clock chip).
Next adapter: SMBus I801 adapter at 1400 (Algorithm unavailable)
Do you want to scan it? (YES/no/selectively):
Client found at address 0x08
Client found at address 0x44
Probing for `Maxim MAX6633/MAX6634/MAX6635'... Failed!
Client found at address 0x4e
Probing for `National Semiconductor LM75'... Failed!
Probing for `Dallas Semiconductor DS1621'... Failed!
Probing for `Analog Devices ADM1021'... Failed!
Probing for `Analog Devices ADM1021A/ADM1023'... Failed!
Probing for `Maxim MAX1617'... Failed!
Probing for `Maxim MAX1617A'... Failed!
Probing for `TI THMC10'... Failed!
Probing for `National Semiconductor LM84'... Failed!
Probing for `Genesys Logic GL523SM'... Failed!
Probing for `Onsemi MC1066'... Failed!
Probing for `Maxim MAX1619'... Failed!
Probing for `National Semiconductor LM82'... Failed!
Probing for `National Semiconductor LM83'... Failed!
Probing for `Maxim MAX6659'... Failed!
Probing for `Maxim MAX6633/MAX6634/MAX6635'... Failed!
Client at address 0x50 can not be probed - unload all client drivers first!
Client at address 0x52 can not be probed - unload all client drivers first!
Client found at address 0x69
Some chips are also accessible through the ISA bus. ISA probes are
typically a bit more dangerous, as we have to write to I/O ports to do
this. This is usually safe though.
Do you want to scan the ISA bus? (YES/no): Probing for `National Semiconductor LM78'
Trying address 0x0290... Failed!
Probing for `National Semiconductor LM78-J'

(confidence 8, driver `it87')
Probing for `IPMI BMC KCS'
Trying address 0x0ca0... Failed!
Probing for `IPMI BMC SMIC'
Trying address 0x0ca8... Failed!
Some Super I/O chips may also contain sensors. Super I/O probes are
typically a bit more dangerous, as we have to write to I/O ports to do
this. This is usually safe though.
Do you want to scan for Super I/O sensors? (YES/no): Probing for `ITE 8702F Super IO Sensors'
Failed! (0x8712)
Probing for `ITE 8705F Super IO Sensors'
Failed! (0x8712)
Probing for `ITE 8712F Super IO Sensors'

Failed! (skipping family)
Probing for `SMSC 47B27x Super IO Fan Sensors'
Failed! (skipping family)
Probing for `VT1211 Super IO Sensors'
Failed! (skipping family)
Do you want to scan for secondary Super I/O sensors? (YES/no): Probing for `ITE 8702F Super IO Sensors'
Failed! (skipping family)
Probing for `Nat. Semi. PC87351 Super IO Fan Sensors'
Failed! (skipping family)
Probing for `SMSC 47B27x Super IO Fan Sensors'
Failed! (skipping family)
Probing for `VT1211 Super IO Sensors'
Failed! (skipping family)
Now follows a summary of the probes I have just done.
Just press ENTER to continue:
Driver `it87' (should be inserted):
Detects correctly:
* ISA bus address 0x0290 (Busdriver `i2c-isa')
Chip `ITE 8712F Super IO Sensors' (confidence: 9)
I will now generate the commands needed to load the I2C modules.
Sometimes, a chip is available both through the ISA bus and an I2C bus.
ISA bus access is faster, but you need to load an additional driver module
for it. If you have the choice, do you want to use the ISA bus or the
I2C/SMBus (ISA/smbus)?
If you want to load the modules at startup, generate a config file
below and make sure lm_sensors gets started; e.g
$ rc-update add lm_sensors default.
To make the sensors modules behave correctly, add these lines to
/etc/modules.conf:
#----cut here----
# I2C module options
alias char-major-89 i2c-dev
#----end cut here----
WARNING! If you have some things built into your kernel, the list above
will contain too many modules. Skip the appropriate ones! You really should
try these commands right now to make sure everything is working properly.
Monitoring programs won't work until it's done.
To load everything that is needed, execute the commands above...
#----cut here----
# I2C adapter drivers
modprobe i2c-isa
# I2C chip drivers
modprobe it87
# sleep 2 # optional
/usr/bin/sensors -s # recommended
Do you want to overwrite /etc/conf.d/lm_sensors? Enter s to specify other file name?
(yes/NO/s): |
And lsmod:

you need I2C enabled in the kernel <*> and then compile the modules for the sensors you need.
ps: <remember to /etc/init.d/lm_sensors start>
this is my config:
kernel .config
| Code: |
# I2C support
CONFIG_I2C=y
CONFIG_I2C_CHARDEV=m
CONFIG_I2C_ISA=m
CONFIG_I2C_SENSOR=m
CONFIG_SENSORS_W83627HF=m
|
/etc/conf.d/lm-sensors
| Code: |
# Load modules at startup
LOADMODULES=yes
# Initialize sensors at startup
INITSENSORS=yes
MODULE_0=i2c-isa
MODULE_1=w83627hf
|

| Yes, i2c support is complied in, with all of the different sensors having been chosen as modules. I did remember to start the service so the modules were loaded. The problem is just that the temperature isn't being shown in the output, as you can see from my first post. |

Taking a quick look in /etc/sensors.conf and doing a search on it87 it looks like you may have to change the temp type.
