A simple and crude driver to play with the hil so-called ``ID module''

devices.

The ID module only purpose is to provide a small, unique, bitstring, which
was used for some copy-protection or licensing scheme under HP-UX.

Right now this driver is useless, as it provides no way to communicate
this information to userland, and only displays it while attaching, as such:
hilid0 at hil0 code 2: ID module
hilid0: security code 10 04 b4 41 ac 77 14 0f 41 00 00 00 00 00 00 00
hilid1 at hil0 code 3: ID module
hilid1: security code 10 04 b4 41 e3 b8 13 0f 41 00 00 00 00 00 00 00

Too bad it's not even good enough to feed the kernel random generator...
