If you are using Lion and want/need to use XP then you may be able to do a "hack" and use the Snow Leopard drivers.
Alternatively run XP under VMware or Parallels (VMware had a special on for 35 US on black friday) or alternatively install windows 7 professional and then get the XP VM machine running under Windows 7 Professional (free seperate download from MSN).
