  i threw all this onto a wiki page, if anyone else wants to play
along:

http://www.crashcourse.ca/wiki/index.php/Atheros_and_localmodconfig

and you're right, of course, it's not a "localmodconfig" thing after
all.

  however, the last bit on that wiki page still puzzles me and i just
noticed it -- even after i manually add in the atheros stuff,
localmodconfig still throws it away again, this time without warning.

  anyway, i know the workaround so i'll go with that. i figure i've
beaten this adequately senseless.
