Hmm. I guess I still don't get it, probably because I haven't read the
NetBSD kernel yet. In a nutshell, how are NetBSD LKM's different from
Linux kernel modules in this respect? I have done a fair bit of module
development in that environment and never encountered a problem like this.
Thanks for being patient. :-)
