because they are two different things.

the kernel cpu is for the ordering of instructions, cache size, etc.

the config cpu is for using specific instructions for the architecture.

With the via epia, you have to configure the kernel as VIAC3-2, and the executables as i686, *NOT AS C3*.

I don't know the correct parameters for other archs.
