The problem is that this table is perpetually outdated. "new" products
come out on a daily basis, quite often nothing more than a rebadged version
of an existing card. At the same time, it wouldn't be the first time that
a product with the same name, model and make suddenly ends up having a 
completely different chipset.

For example; take the card listing from ral(4). It's enormous, and it grows
at a quick pace - but at the same time I'm sure it lists only a portion of the
*complete* list of these cards.

The same applies to a lot of things; cheap USB2 cards, network cards, video
cards, etc. I'm a bit doubtful of the outcome; I'm afraid that a list like
this would list cards which are no longer supported, and leaves out supported
cards.
