Dunno. This driver has a reputation of being the worse wlan driver for
prism2 chipsets out there, but it's the only one supporting USB devices.

To propagate events to scripts, I think:
void    p80211_suspend(wlandevice_t *wlandev)
{
	p80211_run_sbin_hotplug(wlandev, WLAN_HOTPLUG_SUSPEND);
}
int register_wlandev(wlandevice_t *wlandev)
{
	netdevice_t	*dev = wlandev->netdev;
...	if (register_netdev(dev)) {
		return -EIO;
	}
...
	p80211_run_sbin_hotplug(wlandev, WLAN_HOTPLUG_REGISTER);
}

With p80211_run_sbin_hotplug doing stuff to call /sbin/hotplug... 
The one that will write a correct patch to linux-wlan-ng will have to
figure out the different events they use: "register" (instead of "add"),
"startup", "shutdown", "resume", "suspend"...
