Actually, the wi driver does not talk directly to the controller: it
talks to the firmware. But it talks to the firmware directly rather than
using the HCF (hardware control functions) library that Lucent normally
uses. The libhcf library hides most of the hardware details from you.
I chose not to use it because a) the original version of it that I got
from Lucent was contaminated by the GPL, and b) the code is pretty
yucky in my opinion.

That said, the firmware interface is virtually identical for all of
the cards, which includes the 2mbps, 6mbps and 11mbps ones. We're
using the 11mbps gold cards in the office. The Orinoco cards should
just be the same WaveLAN cards with a different name on them.

That may be, but he's not what he said. Read closer: he has a laptop
with a particular cardbus bridge chipset, *not* a PCI card. I've heard
of this problem before, but I don't know if it's directly related to
the wi driver itself. The WaveLAN cards I have work with the laptops
that I've tried here, as well as with the ISA-PCMCIA bridge adapter
cards that came with the Webgear cards.

If I can get my hands on a laptop with that particular chipset, I'll
see if I can debug the problem. The 11mbps cards are supposed to work
though.
