Subject: [2.6.26-git7] ACPI warning (perhaps conflict) on boot with SMBus
 host controler (piix4)

Hello all,

When trying the very latest git kernel (2.6.26-git7) I got this warning 
in dmesg on boot, about ACPI and PIIX4 SMBus controller :

[    4.770406] ACPI: I/O resource piix4_smbus [0xb00-0xb07] conflicts 
with ACPI region SMOV [0xb00-0xb06]
[    4.771726] ACPI: Device needs an ACPI driver
[    4.773035] piix4_smbus 0000:00:14.0: SMBus Host Controller at 0xb00, 
revision 0

But my amd64 box works fine and I haven't notice any dysfunction on it. 
The 26-git6 kernel doesn't cause such a warning.

Regards.
