What is a "VR7 device"?

You can easily check in /sys/class/i2c-adapter if an i2c bus was
created for the PIIX4. Or even easier, run "modprobe i2c-dev &&
i2cdetect -l" as root and see if the PIIX4 SMBus adapter is listed.

If it's not, then the i2c-piix4 driver failed to create the i2c bus.
Are you certain that this is the i2c bus driver you need for your
hardware? Can we see the output of "lspci"? If it is the right driver,
and the driver still fails to create the bus, then I would expect an
error message in the kernel log as you load the i2c-piix4 driver.
