Yes, there is no support yet. We think support could be easily added to
our i2c-piix4 driver, but we would need a datasheet to confirm that. I
just made a request to serverworks to have one, we'll see.

That should be where the I2C/SMBus bus is.
If you like playing with fire, I've attached a simple patch that make
i2c-piix4 accept the CSB6. It could work, since the CSB6 is expected to
be mostly compatible with the CSB5. However, beware that we don't have a
datasheet yet, so the CSB6 may work in a completely different manner,
loading the i2c-piix4 on it may completely screw your system. It's
unlikely, but could happen. I of course take no responsability for that.
