Net died

[Benjamin M. Schwartz]

I have a XO-1.5 (C2 I think).  I logged out of my ssh account, closed  
it up, took it to the airport, turned it on, and it wouldn't find a  
wifi network.  Linux didn't see a network interface, or even try to  
load libertas.  OFW's wlan test fails because it doesn't find the card.

Maybe the card came unseated? Maybe this is a since-resolved  
manufacturing problem? My screwdriver is six time zones away, so I  
can't diagnose further right now.
