The system isn't able to parse the CIS properly, so it asks
individual card handlers to parse it themselves.

Lantern card handler looks for the card manufacturer and product
strings (maybe just the latter) into RecognizedCard method and
compares it with lantern drivers values. These drivers are usually
based on the same template and they register the constants you found.

The card handler is "Newton Devices" package. It is a complete driver
manager and drivers for it come on top of it (they're not card
handlers, hence they don't have a RecognizeCard method for example).
This package also provides Ethertalk services.
This package can be accessed by sending events to drivers. You can
send individual ethernet frames like this, know which driver is
activated in which slot and so on.
NIE Ethernet Module plugs Newton Devices into NIE. This is only for Internet.

The only one I know also comes with a replacement for NIE. And I
think it's because Lantern didn't exist then.
I don't think forcing the Newton to recognize the card would be easy.
If you're lucky, you might be able to write a card handler (like
GetCardInfo) and fill in the CIS data. Maybe in that case the system
will call RecognizeCard method and therefore Lantern will be able to
recognize the card. But that's quite doubtful.
If you want to play in that field, you definitely need Hammer debugger.
