[Bug 42060] Re: Atheros wifi cards appear not to be working in 2.6.25-21

[Robert McMeekin]

This is problem not the answer to your problem, and the package system
probably doesn't allow this to happen, but one thing that could cause
that error was if your linux-restricted-modules package was not compiled
the kernel version you're running.
