It is a 802.11 device with a kill-switch. If you boot the system with the
kill-switch set to disable the device then the wlan0 NIC never appears.
(So to all intents and purposes it's hot-pluggable).
I would have thought the same would apply to any hot-pluggable device - if
I unplugged a CardBus or USB device and then plugged it back in I
wouldn't expect my network configuration to have been erased either.

The same never happened on my old notebook which had a cardbus 802.11 card
- unplugging the card didn't result in the configuration being wiped. I
haven't tried a previous distribution on the machine I'm currently testing
on since it's a brand new machine though.
How is network configuration intended to be persistently stored? This is
more important for 802.11 devices than wired devices since there are
things like the ESSID to configure before it can be used, so the system
can never pick useful defaults. If I unplug an 802.11 device then I would
expect it to reconnect to the network with all the same settings when I
plug it back in.
