[Voyage-linux] ath5k 0.7 troubles

[mgsb]

Hi list

I have one miniPCI wlan card and need two virtual interfaces that I can 
point two instances of hostapd at to make access points.

I have tried the following in /etc/network/interfaces

auto wlan0
iface wlan0 inet static
address 10.0.0.1
netmask 255.0.0.0
pre-up ifconfig wlan0 hw ether 00:88:88:88:00:2A
post-up iw dev wlan0 interface add vap0 type __ap
post-up ifconfig vap0 172.16.0.1 netmask 255.240.0.0
post-up ifconfig vap0 up

This produces a stack trace like so:

I guess I have two questions, the first is for help getting a 
/etc/network/interfaces working for this setup, and the second being I 
though 0.7 had ath9k support, why is ath5k being used?

My wlan card is:

ath5k phy0: Atheros AR5213A chip found (MAC: 0x59, PHY: 0x43)
ath5k phy0: RF5112B multiband radio found (0x36)

Many thanks, grateful for any help
