Which is cool.  (I haven't got a USB key with me, though.  Might still have an 
old pcmcia 802.11b card in one of my backpack's pockets, though.)

But what I really want is an automated regression test harness.  I suppose the 
harness can _simulate_ a hotplug event (by calling mdev with the right 
environment variables set)...
