You can currently only get away living without it if you are just using iwl3945 or iwl4965 as they provide their own rate control algorithms. In the future if other vendor drivers are added with their own rate control algorithm this list grows. Disabling PID will save you some space only on some embedded platforms. Although currently its not evident people would do this I do see this being a reasonable option to keep around for later. Luis
