When you call nxt6000_attach() (say) to attach the frontend, it will determine whether the device is really there or not. If it isn't NULL will be returned, so you can just try the next frontend on your list to see if it works. Several of the drivers do this already : have a look in av7110.c/frontend_init() for an example.
