[lm-sensors] No smbus on asus w1n laptop in spite of quirk > no

[christophe.dr@free.fr (Christophe de Rivière)]

I have reported this problem in many places and searched the internet a long 
time for a solution but i can't find some suitable fix.
The problem is that i can't monitor and control the sensor chip datas because 
of the lack of smbus detection. Yet this problem had been solved about 2 
years ago when i reported it on this list thanks to the help of Jean 
Delvare :

I am using now an old mandriva 2006 with kernel 2.6.12-27 that is properly 
detecting the smbus and it appears on the lspci as :
00:1f.3 SMBus: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) SMBus 
Controller (rev 03) 
But now that i want to jump to a newer distro, none of them is able to detect 
this smbus in spite of the quirks (see above) that is present in the kernel :
$ cat /usr/src/linux/drivers/pci/quirks.c |grep -i w1
                        case 0x184b: /* W1N notebook */
The same lack occured occured on ubuntu 6.10 , suse 10.1, mandriva 2007 and 
suse 10.2 with recent kernels ranging from 2.6.16 to 2.6.18 . No smbus is 
appears on the lspci for any of these distro.
I reported this problem here :

http://qa.mandriva.com/show_bug.cgi?id%281
But i had no answers.
The sensor monitor and fan speed control is a very interesting feature on this 
laptop for battery saving reasons.
I'd be really glad if someone could help .
Or please someone point me to a better place to report this problem.


Thanks.
