That's another issue: the base name is provided by the driver.
Most drivers included in the vanilla kernel use wlanX nowadays, but
older ones or drivers provided from elsewhere (or not yet
well-integrated) often use other names.

For that I added a udev file /etc/udev/rules.d/10-monnier.rules that
overrides the default names.  I've used rules like:

   kernel=="eth*", SUBSYSTEM=="net", DRIVERS=="ipw3945", NAME="wlan0"
   kernel=="ath*", SUBSYSTEM=="net", DRIVERS=="madwifi", NAME="wlan0"
