It turns out that the nut-related hotplug script is executing AFTER
the attempt to load the nut driver, even though the hotplug init script
executes earlier.  Apparently the hotplug system needs to be informed
about nut somehow so that it'll do the right thing at boot, I guess.

The device in question turns out to be /proc/bus/usb/001/002, not
something in /dev/usb/.  Since it's a virtual device, I suspect the
permissions in /dev/usb are irrelevant, and that the hotplug action
is necessary.  Guess it's time to grind through the hotplug code...

If anyone has been through this process for a 2.4 kernel, I'd love
to hear any hints.

TIA,

Jim
