Bug?: Winbond super I/0 chip W83627DHG and nForce2_smbus conflicts with ACPI

I've already asked for help at askubuntu.com but dont know if I should just go ahead an file a bug report.

My problem is that the CPU fan on my HTPC is constantly running af max RPMs

In dmesg I have the following conflict between the modules for the nForce2_smbus and for the Winbond W83627DHG chip

[ 10.856429] ACPI: resource nForce2_smbus [io 0x1c80-0x1cbf] conflicts with ACPI region SM01 [io 0x1c80-0x1cbf]

[ 10.856431] ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver

[ 10.946400] [Firmware Bug]: ACPI(IGPU) defines _DOD but not _DOS

[ 10.948958] ACPI: Video Device [IGPU] (multi-head: yes rom: no post: no)

[ 10.972197] ACPI: resource w83627ehf [io 0x0295-0x0296] conflicts with ACPI region SEN1 [io 0x295-0x296]

[ 10.972200] ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver

Is this a bug in a kernel module I should report? and if so, how should I proceed?

Kind regards,
