ath5k + AP mode?

[Krzysztof Halasa <khc@pm.waw.pl>]

Hi,

Is AP mode with ath5k supposed to work?

My hw:
- IPX425 CPU (ARM architecture - in big- or little-endian mode)
- Wistron NeWeb Corp. CM9 a/b/g MiniPCI (AR5001X+, PCI IDs 168c:0013 +
  sub 185f:1012).
- hostapd from git (f4f2774a96d91753811e921380856bc859888153)
- linux from git (basically wireless-testing = master-2008-12-12)
