VirtualBox piix4_smbus Error

VirtualBox 3.2.10 gives me the following error message when booting Ubuntu 10.10:-
piix4_smbus 0000.00.07.0: SMBus base address uninitialized - upgrade bios or use force_addr=0xaddr


This error is caused by VM having no smbus but Ubuntu always trying to load the module. It doesn't affect anything but is a bit annoying - to fix...
