For those with the Atheros 5007 card, unfortunately, the 2.6.25 kernel requires a patch for the Madwifi source to build.
Also unfortunately, this patch breaks the patched snapshot that works with the AR5007EG card.
However, the encouraging news is that judging from the Madwifi ticket 1679, (probably familiar to all with the card) soon the patches for the 5007EG card will become part of the stock Madwifi.
This isn't something that I'd consider a bug on anyone's part, save perhaps for Atheros, for making it so hard to get this card work with Linux. I would consider it more of an unfortunate situation.
At any rate, for those who do have machines with that card, and who are still following rawhide, this information might be useful.
