Well, the one obvious problem, if one isn't careful about it, is that serial devices present before the module is loaded won't bind properly. The usb driver will get probed before the usb_serial driver is registered, and the probe will fail. I can fix that easily enough by calling driver_attach() for the usb driver after all the usb_serial drivers are registered.
