Today, due to the heat, I tried to make lm-sensors work on my ASUS A7V 
KT133 motherboard in order to check the temperature (One fan already 
died without damaging the processor...).

Hi,

At least I suceeded to make lm-sensors work on ASUS A7V but encountered 
the following problem : i2c-viapro.c tries to request an ioports region 
(in my case 0xe800 see <====) that has already been allocated by the 
acpi motherboard.c code and fails whith an error if this region has 
already been allocated.

I first tried to use the "force_addr" methods in i2c-viapro.c using a 
free ioport location but then lm-sensors works but code breakes ACPI 
support (fails to shutdown at least) as it reprogram the bus chip base 
address without ACPI code being notified.

With the following patch targeted toward 2.6.8-rc2-mm2, both things 
works together like a charm. I have no idea if patch is correct but at 
least I think the analysis is. Let me know if you think there is a 
better fix.
