I tested this case on my own system and I could load both modules, and
both seemed to work (lm_sensors-2.8.0). I think I remember seeing
something about that on the mailing list recently:
Modified Files:
i2c-voodoo3.c i2c-via.c i2c-viapro.c i2c-i810.c i2c-savage4.c
Log Message:
(mds) don't use pci_module_init() for video i2c drivers so we don't
conflict with video drivers
It was for a different conflict (it seems). However, the changes made to
i2c-viapro.c may also prevent the conflict you observed. This is a very
recent change (occured on July 2nd.). I attached the patch, could you
please check wether it is already applied to the 2.6.0 kernel tree? If
not, could you try to apply it and tell us if it solves your problem?
I admit I'm a bit confused, because i2c-viapro is a bus driver while
via686a is a chip driver. Thus I wonder how they can conflict...
However, the driver registering mechanisms of the Linux kernel is beyond
me, so it may just be me ;)
