Title:
  Resource conflict in modules it87 and asus_atk0110

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  The PWM fan control system needs the IT87 module. In former kernel versions before last week's update to linux-image-3.0.0-16-generic  #29 it was loaded in parallel to asus_atk0110  either by itself or using the kernel boot parameter:
  acpi_enforce_resources=lax
  As of last week's update, using above parameter loads IT87 but prevents asus_atk0110 from loading, giving the error msg:
  asus_atk0110: Resources not safely usable due to acpi_enforce_resources kernel parameter.

  On top, dmesg has the following info:
   ACPI: resource it87 [io  0x0295-0x0296] conflicts with ACPI region ECRE [io 0x290-0x2af]
   ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver
