Are you using a particularly old kernel? This was patched years ago to only include ALI in INIT{_ACK} if the user has specified a valid (i.e. non-zero) application code-point. http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=6fc791ee631728b2beddda87560f1af59e32230e Cheers, malc.
