I bought one of these last night after reading in wi(4) that the Linksys
Instant Wireless cards are supported by NetBSD.  This one doesn't seem
to be.  If you can prove me wrong, please write to me.

It turns out that this is a Cardbus card.  The other Linksys cards
supported by wi(4) are PCMCIA cards.

When I plug in the card, this is what NetBSD says:

Realtek, Rtl8139, [FF][FF] (manufacturer 0x0, product 0x0) Realtek
Semiconductor product 0x8180 (ethernet network, revision 0x20) at
