support for p4s8x motherboard

Hello,

I have a P4S8X motherboard from Asustek.
My system is Mandrake 9.1 with the latest 2.4.21 kernel from Mandrake 
Update. I have just install the latest i2c and lm_sensors from CVS but I 
am not able to make them work (Your web site announce that these 
combination - 648/961 - should be supported with the CVS version). I am 
not a developper so I can't help you much but here is the results of the 
different commands.
I hope it can help you improve your code.
Thanks.

  This program will help you to determine which I2C/SMBus modules you 
need to
  load to use lm_sensors most effectively.
  You need to have done a `make install', issued a `depmod -a' and made sure
  `/etc/conf.modules' (or `/etc/modules.conf') contains the appropriate
  module path before you can use some functions of this utility. Read
  doc/modules for more information.
  Also, you need to be `root', or at least have access to the 
/dev/i2c[-/]* files
  for some things. You can use prog/mkdev/mkdev.sh to create these /dev 
files
  if you do not have them already.
  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.

  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-sis645' for device 00:00.0: Silicon Integrated Systems 
SIS648
Probe succesfully concluded.

  We will now try to load each adapter module in turn.
Module `i2c-sis645' already loaded.
  Do you now want to be prompted for non-detectable adapters? (yes/NO): yes
Load `i2c-elektor' (say NO if built into your kernel)? (YES/no):
modprobe: Can't locate module i2c-elektor
Loading failed... skipping.
Load `i2c-elv' (say NO if built into your kernel)? (YES/no):
/lib/modules/2.4.21-0.18mdkcustom/kernel/drivers/i2c/i2c-elv.o: 
init_module: No such device
Hint: insmod errors can be caused by incorrect module parameters, 
including invalid IO or IRQ parameters.
       You may find more information in syslog or the output from dmesg
modprobe: insmod 
/lib/modules/2.4.21-0.18mdkcustom/kernel/drivers/i2c/i2c-elv.o failed
modprobe: insmod i2c-elv failed
Loading failed... skipping.
Load `i2c-philips-par' (say NO if built into your kernel)? (YES/no):
Module loaded succesfully.
Load `i2c-velleman' (say NO if built into your kernel)? (YES/no):
/lib/modules/2.4.21-0.18mdkcustom/kernel/drivers/i2c/i2c-velleman.o: 
init_module: No such device
Hint: insmod errors can be caused by incorrect module parameters, 
including invalid IO or IRQ parameters.
       You may find more information in syslog or the output from dmesg
modprobe: insmod 
/lib/modules/2.4.21-0.18mdkcustom/kernel/drivers/i2c/i2c-velleman.o failed
modprobe: insmod i2c-velleman failed
Loading failed... skipping.
  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).
