In i810_setup(), i830_setup(), and i9xx_setup(), we use the result of pci_bus_address() as an argument to ioremap() and to compute gtt_phys_addr. These should use pci_resource_start() instead because we want the CPU physical address, not the bus address. If there were an AGP device behind a host bridge that translated addresses, e.g., a PNP0A08 device with _TRA != 0, this would fix a bug. I'm not aware of any of those, but they are possible.
