I realised that it is now (Max/MSP 4.6) possible to unconnect an audio interface, and later reconnect it, choose the driver again (still remains in the menu) and it works. Great! But there is nothing which could be done better:

As Max obviously recognises the change of the driver (I get a message in the Max window). It could update the menus filled by adstatus automatically. That would allow to add an interface without the need of restarting Max. (Sure its not really urgent ;-)

If I set the Powerbook (1.5 GHz PPC) to sleep, I still need to choose the driver once, to reset it and it will work after that. Wouldn't it be possible to automate this as well? .......

Ah, when I think about it, I can patch it (with a simplified version of my wakemess abhaXion):
