Re: hotplug TTD

        Perhaps I'm just being pedantic, but I'd like to just clarify
that many of the Linux-related facilities that people refer to as
"hot plugging" in are not really hot plugging, but rather a set of
facilities used by most of the kernel hot plugging schemes:

                1. a standardized hardware identification scheme
                   for the bus in question (ISAPnP, PCI, USB, other
                   systems covered by Intel Plug'n'Play standards, etc.)

                2. a facility for dynamically loading kernel driver
                   modules for that bus.

                3. A MODULE_DEVICE_ID table for that format in each
                   relevant driver.

                4. Support for that ID table format in depmod
        
                5.  A user level program that reads the appropriate depmod
                    modules.___map and figures out which modules to load.

        For example, I understand that ISAPnP hardware is not
capable of hot plugging, but it uses these same facilities.
Conceivably, other non-hotplug busses that have quasi-standard
schemes for hardware enumeration could use these facilities
as well (NuBus? S-Bus?).
