I think the 2.4 definition will be fine - at least for now. Was there a 
reason it was changed in 2.6 ?

2.4 definition:
struct pci_controller {
        void *acpi_handle;
        void *iommu;
        int segment;

        unsigned int windows;
        struct pci_window *window;

        void *platform_data;
};
