Title:
  [Lucid] kernel 2.6.32-22 module i2c-core missing

Status in “linux” package in Ubuntu:
  Triaged

Bug description:
  When trying to further dig into bug #575296 (no module for 2nd i2c-bus
  on ASUS nForce boards), I had to realize that in Lucid's kernel the
  module

  i2c-core

  is missing. So I cannot force to load module i2c-nforce2 at address
  0x1c40 (like Hardy does automatically). This results in following
  error message on boot-up Lucid:

  ACPI: resource nForce2_smbus [0x1c40-0x1c7f] conflicts with ACPI region SM00 [0x1c40-0x1c45]
  ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver

  While Hardy correctly assignes the i2c-nforce2 to both i2c-busses:

  i2c-adapter i2c-0: nForce2 SMBus adapter at 0x1c00
  i2c-adapter i2c-1: nForce2 SMBus adapter at 0x1c40

  In Hardy module i2c-nforce2 depends on i2c-core, not so in Lucid.
  Lucid only provides i2c-core for the EC2-kernel:

  apt-file search i2c-core
  	linux-image-2.6.32-305-ec2: /lib/modules/2.6.32-305-ec2/kernel/drivers/i2c/i2c-core.ko
  	linux-image-2.6.32-306-ec2: /lib/modules/2.6.32-306-ec2/kernel/drivers/i2c/i2c-core.ko

  As a result I cannot pass any arguments to i2c-core to bind to a certain I/O.
