Now that I successfully installed NetBSD on my MVME147, I want to write 
some drivers to access the special hardware of our data acqusition 
system.  Since I never did that on a Un*x system, I need some help and 

I was looking for a nice .tgz file with the kernel and driver sources, to 
get a template how this is done for the NetBSD mvme68k port, but it seems 
that getting the sources at all is not straight forward.

The MVME147 is designed for such applications, so this should not be 
something uncommon.

 1. Is it necessary to recompile the kernel to access extra hardware on 
    the VME bus? ... to install interrupt service routines?

 2. Can somebody point me to some template sources, how to do the job?  
    Is there documentation available on this kind of problems?
