Before trying to change things you may want to try wireless-testing or compile from compat-wireless as that is where we have our latest and greatest. You can read about how to get the wireless-testing tree using git here: http://wireless.kernel.org/en/developers/Documentation/git-guide With compat-wireless you just download the wireless framework and drivers and get to compile it for older kernels: http://wireless.kernel.org/en/users/Download Luis
