I'm using zd1211rw device and bringing interface up before setting ESSID and KEY for wireless device did not cause any problem for me using different hardware as well. That was not an issue with vendor driver, but it's necessary to bring interface up for rewrite of the driver. Thus, I was not sure if this related with driver or the network-scripts. But considering zd1211rw is included with kernel, it's evident that without necessary changes on ifup-wireless it's not possible to automatically bring interface into running state. If someone states a bug id, i can submit my change(s).
