Current HAL requires that the device respond successfully to the
SIOCGIWNAME WEXT ioctl, and that it have the correct bits in sysfs to
relate the netdevice (ie, wlan0) to it's parent device.  So you'll want
to make sure that you have a /sys/class/net/wlan0 directory (or whatever
the interface is named), and that in that directory there's a valid link
called "device" that points to the PCI or USB device in /sys that
provides that net interface.
