The resource allocator doesn't care. Just find the places where the I/O flag is checked and the limit is set to 0xffff and try setting it larger. I would look in src/devices/pci_device.c and src/northbridge/your_northbridge/northbridge.c first. I'm not sure what will break, but we should be able to fix it pretty easily.
