Compaq R4000 laptop, Yenta driver said "Fish. Please report this."

Hello.

The above message was entertaining enough that I thought I would do as
the message asked, and report the bug.

My friend has a Compaq R4000 laptop, and wishes to run Linux on it.
Being the helpful type, I helped them through a few kernel hoops (the
onboard keyboard isn't AT...), and then we had problems getting
ndiswrapper working for either of the onboard network cards (which
were crap, but I'll get back to this later).

We finally went out today, got a DWL-G630 rev. C2, and put it in the
laptop. Not detected, at all. lspci shows no change. Plug it into my
far more compliant laptop, and it's immediately detected as an Atheros
chipset device and works fine.

This led to research, which lead to the following message from initial bootup:
Yenta: CardBus bridge found at 0000:03:04.0 [103c:3085]

Here, have the lspci output:

Since the above message was so obscure and entertaining, I decide to
report it, and see if anyone had a fix. Kernel 2.6.12.3, apparently on
amd64 arch (the processor is a latest-gen Sempron, which Wikipedia and
Google claim is an AMD64-based processor without the 64-bit, which
sucks.)

Thanks for taking the time to read this, and for putting out a great
codebase for all of us to use. :)
