NgATM is MPSAFE to the extend that netgraph is MPSAFE. The drivers I've 
written are MPSAFE too to the extend the interface driver framework is 
MPSAFE (think of calling interface routines while the driver is unloading 
and so on. There was some discussion about how to fix this, but it's still 
there).

Ok. I'll do that today.
