Atheros guys themselves recommend removing and re-inserting the driver
stack as the way to get the WLAN device recognized again after depower.
~ Yes, that's the vendor recommendation.

I believe it too, because I actually implemented the power switching
stuff and found that WLAN was never subsequently recognized after
powering it, and went and asked the Atheros guys.

So... unless we:

~ - fix the Atheros stack, or,

~ - throw out the Atheros SDIO stack, which there is some little hope
about, and the mainline one acts better

modprobe-cycling the existing stack is the way forward, and something we
can do to improve things today.
