    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_!
