We finally solved this problem!!!
There is some action that Composer 7 takes when crunching an OS image
that breaks the wireless configuration. We built the same image again
and used Composer 6.01, which resulted in a larger DMG and took a much
longer time, but the result was an image with functional Airport drivers
and configuration.
