much better,
Because don't need to cast conf to drivers_pci_onboard_config, it is not
safe in pci_rom.c or pci_device.c

Do it.

How about we bring the device:rom_address back and in the 

driver_pci_onboard::enable_dev(dev)
{
	dev->rom_address = conf->rom_address;
}

and in 
pci_get|set_resources()
{
	if (dev->on_mainboard && dev->rom_address !=0) {
		/* do nothing */
	else {
		allocate_rom_resource();
	}
}

and in pci_dev_init()
{
	if (dev->on_mainboard && dev->rom_address !=0) {
		rom = dev->rom_address;
	else {
		rom = pci_rom_probe();
	}
}
