i have spent several hours trying to figure out how to setup lm-sensors. i have slowly made progress, and was almost able to achieve complete success. i am not sure though if i made the correct steps. let me share my experience in the hope that you could help me sort this one out.

a) system

   - Ubuntu Dapper
     2.6.15-26-386

   - compiled lm-sensors.2.10.0

   - pertinent output of lspci
     -------------------------

	0000:00:1f.3 SMBus: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) SMBus Controller (rev 04)

b) pertinent output of sensors-detect
   ----------------------------------

Probing for PCI bus adapters...
Use driver `i2c-i801' for device 00:1f.3: Intel 82801FB ICH6
Probe succesfully concluded.

...

Next adapter: SMBus I801 adapter at 1400
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 0x50
Probing for `SPD EEPROM'... Success!
    (confidence 8, driver `eeprom')
Probing for `DDC monitor'... Failed!
Probing for `Maxim MAX6900'... Failed!
Client found at address 0x52
Probing for `SPD EEPROM'... Success!
    (confidence 8, driver `eeprom')
Client found at address 0x69

...

#----cut here----
# I2C module options
alias char-major-89 i2c-dev
#----cut here----

To load everything that is needed, add this to some /etc/rc* file:

#----cut here----
# I2C adapter drivers
modprobe i2c-i801
# I2C chip drivers
modprobe eeprom
# sleep 2 # optional
/usr/local/bin/sensors -s # recommended
#----cut here----

c) the following modules were loaded:

$ lsmod |grep i2c

i2c_dev                 9984  0
i2c_i801                9100  0
i2c_core               21904  2 eeprom, i2c_dev,i2c_i801

problem started when i used "sensors". the results came out as 

Can't access procfs/sysfs file
Unable to find i2c bus information;
For 2.6 kernels, make sure you have mounted sysfs and libsensors
was compiled with sysfs support!
For older kernels, make sure you have done 'modprobe i2c-proc'!

c) i tried playing around with i2cdump using the addresses of devices i got with "sensors-detect"

c1) results of "i2cdump 0x08"

d) i tried to guess what chip/device to use. i experimented with adm1021:

d1) modprobe adm1021 force=0,0x08

"sensors" give:

max1617-i2c-0-08
Adapter: SMBus I801 adapter at 1400

Board:        -1?C  (low  =    -1?C, high =    -1?C)  ALARM (LOW,HIGH)
CPU:          -1?C  (low  =    -1?C, high =    -1?C)  ALARM (N/A,LOW,HIGH)

d2) modprobe adm1021 force=0,0x44; "sensors" give

lm84-i2c-0-44
Adapter: SMBus I801 adapter at 1400

Board:        +0?C  (low  =    +0?C, high =    +0?C)
CPU:          +0?C  (low  =    +0?C, high =    +0?C)

d3) modprobe adm1021 force=0,0x50; "sensors" give

Can't access procfs/sysfs file
Unable to find i2c bus information;
For 2.6 kernels, make sure you have mounted sysfs and libsensors
was compiled with sysfs support!
For older kernels, make sure you have done 'modprobe i2c-proc'!

d4) same results with modprobe adm1021 force=0x052

d5) modprobe adm1021 force=0,0x69

max1617-i2c-0-69
Adapter: SMBus I801 adapter at 1400

Board:       +15?C  (low  =   +15?C, high =   +15?C)
CPU:         +15?C  (low  =   +15?C, high =   +15?C)  ALARM (N/A,LOW)

This last seem to be the closest. But for sure, it gives me incorrect information (15?C for CPU!)...

Am I doing the right thing?

I wish someone could help. Thanks!
