Noticed that my zd1201 adapter isn't "seen" by hal and NetworkManager.
The problem seems to be that unlike other network device drivers I
checked, zd1201 does not do a SET_NETDEV_DEV(), which makes it so a
"device" symlink is created under /sys/class/net/wlan0.

With the following patch the device symlink shows up, and now I am
happily using NetworkManager to control the adapter:

$ ls -l /sys/class/net/wlan0
total 0
