i am not so deeply into kernel and hotplug, but to my knowledge, plugging in
the prism54 card (a presume you have a cardbus-WLANNIC) calls /sbin/hotplug
and hotplug will load the prism54 driver and consequently manages the
firmware upload to the card (this might also be the other way round)... but i
think the developers on this list can provide you deeper information...
