Just to clarify things a little for those following it: the original I4B code 
was removed for entirely practical reasons: it couldn't run without the Giant 
lock, and support for the Giant lock over the network stack was removed.  I'm 
happy to see ISDN support reintroduced as long as it will see ongoing 

I'm not familiar with Hans's most recent code, but the integration of his USB 
stack and his recent receipt of a FreeBSD commit bit suggest a promising 
future.  I would suggest trying to rope in a reveiwer and collaborator 
(perhaps someone like Bjoern Zeeb?) to work through it before considering a 
merge, however.  This is especially important with projects like VIMAGE, 
network stack parallelism projects, etc, on-going to make sure that the new 
ISDN code will be able to support these new features rather than become a 
potential obstacle (as the old code did for the MPSAFEty work).
