I doubt it'll hurt anything. The power savings bit are more or less all left to userspace now, and you can toggle something in /sys more than likely to disable it on the keyboard (as was mentioned already.) It's probably best to write a udev rule specifically for your keyboard (and mouse, while you're at it) if you want to go that route. Dan
