I already tried to file this report on the 
http://www2.lm-sensors.nu/~lm78/support.html
page but for some unknown reasons it doesn't seem to register my ticket.
Here is the ticket i wanted to submit to the database :


I have googled a lot and searched the database and FAQ(section 5.3) but i
found no answer to my problem. The adt7463 on my asus w1n laptop / mandrake
10.1 Official Edition is not detected in spite of all my efforts.

I found nothing consistent in the logs.

Interesting part of sensors-detect :
- ----------------------------
...
  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): YES
Probing for PCI bus adapters...
Sorry, no PCI bus adapters found.

We will now try to load each adapter module in turn.
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 not loaded. Do you want to load it now? (YES/no): YES
 Module loaded succesfully.

 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).

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): YES
Probing for `National Semiconductor LM78'
  Trying address 0x0290... 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): YES

 Sorry, no chips were detected.
 Either your sensors are not supported, or they are
 connected to an I2C bus adapter that we do not support.
 See doc/FAQ, doc/lm_sensors-FAQ.html, or
 http://www2.lm-sensors.nu/~lm78/cvs/lm_sensors2/doc/lm_sensors-FAQ.html
 (FAQ #4.24.3) for further information.
 If you find out what chips are on your board, see
 http://secure.netroedge.com/~lm78/newdrivers.html for driver status.

Actually i ran speedfan on windows XP and it finds a ADT7463 (it says ID $27)
on an smbus ($2E address). It also says ISA bus at $0290 and SMBUS at$0540
(intel 82801DB).

I tried to insert manually various modules like i2c-i801, i2c-i810,
i2c-sensor, i2c-piix4, i2c-isa....
I also tried to insert the lm85 module corresponding to the adt7463 sensor
chip. I tried many different parameters, but i don't know how to pass a
correct parameter described as :
"List of adapter,address pairs which are unquestionably assumed to contain a
`adt7463' chip"
in this document :
http://www2.lm-sensors.nu/~lm78/cvs/lm_sensors2/doc/chips/lm85

I suppose the problem is that there is no bus to reach the sensor. (SMBus ?
i2c ? Isa ???). But i have no clue on how to solve this.

i2cdetect gives nothing. i2cdump gives nothing.

isadump gives only zeros.

I can't read what's on the chip because it's a laptop and i would lose
warranty if i open it.

I don't know motherboard type but lspci above will tell you.

Sensor version is 2.8.7

Kernel version is 2.6.8.1

I need this lm_sensor to lower the fan speed in order to have more battery
time.

Thank you
