+Description
+-----------
+
+i2c-nforce2 is a driver for the SMBuses included in the nVidia nForce2 MCP.
+
+If your 'lspci -v' listing shows something like the following,
+
+00:01.1 SMBus: nVidia Corporation: Unknown device 0064 (rev a2)
+        Subsystem: Asustek Computer, Inc.: Unknown device 0c11
+        Flags: 66Mhz, fast devsel, IRQ 5
+        I/O ports at c000 [size=32]
+        Capabilities: <available only to root>
+
+then this driver should support the SMBuses of your motherboard.
+
+
+Notes
+-----
+
+The SMBus adapter in the nForce2 chipset seems to be very similar to the
+SMBus 2.0 adapter in the AMD-8111 south bridge. However, I could only get
+the driver to work with direct I/O access, which is different to the EC
+interface of the AMD-8111. Tested on Asus A7N8X. The ACPI DSDT table of the
+Asus A7N8X lists two SMBuses, both of which are supported by this driver.
