Get the lm_sensors 2.6.2 or more recent: http://www.lm-sensors.nu/archive/lm_sensors-2.6.2.tar.gz You'll need kernel sources too in order to compile that one.
tar -xzvf i2c-2.6.2.tar.gz
cd i2c-2.6.2
make && make install
Then there was a problem when making install for me, so if it doesn't work, just do the following:
cp kernel/i2c-core.o /lib/modules/`uname -r`/misc/i2c-core.o
cp kernel/i2c-proc.o /lib/modules/`uname -r`/misc/i2c-proc.o
Now let's copy the specific driver:
cp kernel/chips/it87.o /lib/modules/`uname -r`/misc/it87.o
ok now
cp prog/sensors/sensors /usr/bin/sensors
--------------------------------------------------------------------
Edit /etc/modules.conf and add to it the following lines:
alias char-major-89 i2c-dev options it87 temp_type=0x31
now:
modprobe i2c-proc
modprobe it87
modprobe i2c-isa
sensors
should output you some data
When it works, you can write it to a file, that will be loaded automatically on boot. Under SuSE the file is: /etc/init.d/boot.local (used to be /sbin/init.d/) and you should just add: sensors -s Under mandrake, the install should have created that file: /etc/init.d/sensors, which you can edit freely, sensord being just a daemon to watch over temperature and fan speed, I assume no one will need something like that for her/his own machine.
Paolo reports that in order to start up sensord on boot, he put in /etc/sysconfig/sensors:
MODULE_0=i2c-proc MODULE_1=it87 MODULE_2=i2c-isa
Now as root you should edit your /etc/sensors.conf search for that line: chip "it87-*" and below you should be able to modify everything to get the right data, here is a copy of what i have in there: (please note that temp1 is trash and only temp2 and temp3 should be kept)
--------------------------------------------------------------------
This time you'll be forced to compile the modules. install the source and programs:
apt-get install lm-sensors lm-sensors-source
Answer yes to this question, you can't have an IBM thinkpad and the k7s5a in the same box as far as I know!The upstream lm-sensors maintainers know of a problem using lm-sensors with IBM ThinkPad computers, resulting in firmware corruption. If you are installing this package on a ThinkPad, you should wait until the upstream maintainers have solved this problem before building modules from it. For more information, see /usr/share/doc/lm-sensors-source/README.thinkpad. IBM ThinkPad brokenness -- really install lm-sensors?
cd /usr/src
tar xzvf lm-sensors.tar.gz
cd modules/lm-sensors/
make && make install
Then you should have modutils take a few arguments, the best way is probably to use a new file, like: /etc/modutils/sensors with this content:
runalias char-major-89 i2c-dev options it87 temp_type=0x31
update-modules
modprobe i2c-isa it87
You can now type sensors to access to the informations (note that you should edit sensors.conf, otherwise you'll see strange and inaccurate things :] )
You can also put i2c-isa and it87 in /etc/modules (one by line!) to have them be automatically loaded on boot, I don't know yet, how/whether it is possible to use some automatic loading/removing process with /etc/modules.conf

mount sysfs pseudo filesystem if you have not done it yet.
mount -t sysfs sysfs /sys
See Documentation/filesystems/sysfs.txt and Documentation/i2c/sysfs-interface in the kernel sources tree
modprobe it87
modprobe i2c-isa Sensors can be accessed in the sysfs pseudo file system. But if you want you can use the lm_sensors user tools...
Install sensors user tools:
cd lm_sensors-2.8.3
copy this into a file named chips-it87.diff
