ORBIT-USER: Where's the WiFi device on sb2?

[Sachin Ganu]

Einar,

You will need to load the driver using "modprobe ath_pci" prior to
bringing the interface ath0 up. The nodehandler does this
automatically. Also, at the end of the experiment, the nodehandler
unloads the driver.

At the end of your slot, I will try to test "nodehandler -t -k " and
see if I can recreate the problem.
