udev just calls either usb_modeswitch or eject at the hotplug event.  So,
you always need an update to the udev database, regardless.

The choice between using usb_modeswitch or eject is really one of "does the
standard eject work properly" or not.  If not, add the code to
usb_modeswitch.  Tho, if the usb_modeswitch maintainers want to carry
around a duplicate set of 'eject' code, that's really up to them.
