  I know we have been through this before, but perhaps without any
resolution. Certainly none that I'm aware of.

  I am just updating my IPsec development tree to 1.2G from Friday.

  I notice that the major device number that I was using is not the
planetconnect satlink device. No big deal, I can patch, but it really
annoys me that I need a private copy of conf.c.
  [I realize that most of arch/foo/foo/conf.c could be generated,
but I don't think we are ready for that yet]

  This is what I'd like to propose: conf.c will include two files
if a kernel compile option is set. The first file should contain
additional #includes and cdev_decl, and cdev_foo_init's if required.

  The second file contains the necessary stubs for cdevsw.

  Now, to avoid the problem with major numbers changing, I propose
that we pad cdevsw with a bunch of reserved numbers. We are at minor
number 45 on the i386. Do other ports have much higher values? I
padded up to minor number 64, and then put the include for the cdevsw.
[oops, it is zero based. I should have stopped at 63]

  That way the first "custom" number occurs at 64, and will remain
like that for at least a release or two.

  It is PR #kern/4094.
