ipw2200 firmware

Hi , I am trying to update the firmware from 2.2 to the current version 2.3 of ipw2200. I have downloaded the firmware from ipw2200.sourceforge.net, unpacked the files and copied them to the /lib/firmware directory, but SuSE still loads the 2.2. If I delete the 2.2, it can't find the firmware on boot. What controls which file is loaded for the firmware? and how do I changed it? -- Thanks http://www.911networks.com
