Here is an updated patch addressing most of Uwe's and Peter's

comments. Ripping out the ehci/uhci_init() code doesn't seem to have                                                                                                                         
done any harm, and I got rid of a bunch of unused junk in                                                                                                                                    
i3100_smbus.h                                                                                                                                                                                
                                                                                                                                                                                             
I left the *_set_subsystem() arguments unsigned, as that's how the                                                                                                                           
function is declared in include/device/pci.h.
