Yep, it works without any problems...
Install the wireless-tools to set it up (with iwconfig), and you can use
it.

I'm not an expert, but I think orinoco cards works fine and have an
external antenna plug. It can be usefull...

I have an airport card in my ibook, and I have used non-apple bases
without problems.It's just a matter of channels. My card is a french
one, so I only have access to channels 10 to 13. If the base is a US
one, on channel 6 for instance (very common), it can't work, you have to
switch it to channel 10. Unless if someone know how to "extend" an
airport card (in which case I am _very_ interested...)

Sounds like the same to me. However, the firmware in the wireless card
in the base is somewhat different. ( Yes, open a base, and you will
probably see a pcmcia connector with a standard 802.11b card in it ;-).
There is a few more electronics, but the radio part is there...). If the
firmware is the same, you will have to run in "Had-Hoc" mode which is
less interesting...

Yes, but I _think_ (not an expert though), you will have to flash the
card. Instead you will have to be in "Ad-Hoc Mode" which one permit to
clients to talk together without a base. But this mode doesn't support
stats so no signal strength and so on... But I'm sure it's doable...
