Of course I tried that, but for every instance I listed, there were
reasons that the kernel modules refused to unload.  I've seen PCMCIA, NFS,
USB, and others refuse to unload even when every process short of init and
sh were kill -9'ed.

Still, there's always the possibility that I missed something.  Anyone
know of a good reference on how to find the processes using a kernel
module?  fuser is good if you know the files the process opens, but what
if you don't?
