Well, it seems that it should be supported just fine in kernels after 2.6.28. Unfortunately, it appears from distrowatch that Privatix Live-System has a 2.6.26, which means it must be based on Lenny (oldstable).
You can try following the directions for Lenny (i.e. using Lenny backports
). Otherwise, you'll probably have to compile your own kernel, and possibly the wireless-tools.
