If all devices can handle 66MHz, then use 66MHz. Triple the number of configured I/O ranges that we can handle on a bus (8 was insufficient--originally didn't consider multifunction devices) Allow one to specify which types of memory to configure, I/O, ROM, or MEM--for example, one could configure only ROM or only non-ROM. Ensure that the ROM is disabled if we're not configuring it. Only set PCI_COMMAND_IO_ENABLE/PCI_COMMAND_MEM_ENABLE if there are valid memory ranges configured.
