I saw in another thread where you've upgraded kernels before, but apparently that was on VL Standard -- or at least not Light, as VASM CC was mentioned.
9k, apparently including usb, is in 188.8.131.52. At least that's what locate ar9170 gives me.
I'm using this kernel, but not this particular Atheros. Since switching kernels, shutdown can't power down the laptop unless wicd has wlan0 associated with an AP, but my VIA is known to be flaky with several power issues; may be kernel, mainboard, ath, or wicd. Dunno.
