Here's the lspci for the SR71-A that doesn't work with ath9k:

03:00.0 Ethernet controller: Atheros Communications Inc. AR5008 Wireless Network Adapter (rev 01)
	Subsystem: Atheros Communications Inc. Device ee1c
	Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV+ VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx-
	Status: Cap+ 66MHz+ UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx-
	Latency: 64, Cache Line Size: 32 bytes
	Interrupt: pin A routed to IRQ 15
	Region 0: Memory at febf0000 (32-bit, non-prefetchable) [size=64K]
	Capabilities: [40] #80 [0000]
	Capabilities: [80] #00 [0000]

The only visual difference we saw is that there is a chip labeled AR9160-AC1E
on the one above, and the ones that work have instead:  AR9160-BC1A

The SR71-A that *does* work, works very well for us.  The problem is just that we
cannot be sure of what we are receiving when we order stuff because the name
is the same for both NICs.

Thanks,
Ben
