I guess the IBM kit is this:

It comes with 2 PC cards, but you need to plug one to the hub, and it doesn't mention the speed and what standard it uses and no NT/Win2000 driver. I guess it is not 802.11b.
But it is funny, in the description it says:
- Surf the internet from the toilet, or the deck, or anywhere!
YA! It is the wireless all about!
