I can now answer my own question: It's a design flaw within kde's laptop daemon. This thingy checks for keyboard and mouse events through parsing /proc/interrupts, searching for the keywords "[K|k]eyboard" and "[M|m]ouse" and checking whether or not interrupts have occurred. Thus, no wonder the usb mouse doesn't count so to speak; in /proc/interrupts the usb mouse does not appear as "mouse" but as "usb-ohci" (or whatever driver you use) - and might as such share irq with other devices (such as sound in my case). :( I will file a bug because this is obviously not a good way - considering some people using USB input devices only.
