Having _actually_ dealt with a non-devfs driver under devfs:
1. I had to make 0(zero)(NULL) changes for the driver to work
with devfs. None. Nada. Not a line, character, or bit.

2. Once devfs was installed I was able to make significant
behavioral changes with many fewer lines of code than
those changes would otherwise have taken. Less debugging,
cleaner result.

3. It wasn't until several weeks _after_ I had hacked all of
this that I noticed that there were special functions
available for devfs that would have let me do _more_!
