It's not a very good solution, but you can use pci-stub to claim both devices, then manually unbind each from pci-stub and bind it to the driver you want. Compile pci-stub statically so it gets first dibs (CONFIG_PCI_STUB=y) and boot with pci-stub.ids=xxxx:yyyy where x/y is vendor/device ID. Use sysfs to unbind the device you want, load the driver, repeat for the second device & driver.
