Public bug reported:

I have a Terratec Cinergy 600 tv card with a Philips FM1216 tuner (and a 
Philips SAA7115 video decoder). 
Somehow the card causes keypressed to be sent to the system. It happens 
irregularly, the problem can go away for weeks and then suddenly occur several 
times per hour.
My computer detects a key press although I don't type anything. I've tried 
several keyboards and it doesn't even stop when I unplug the keyboard (all 
PS/2, I don't have a USB keyboard). I also removed about everything else from 
my computer. It only stops when I remove my tv card, so I'm quite sure it is 
the cause. 
The key is always '0' on the numpad (KP_0) or insert (KP_Insert) if I turn off 
numlock. It behaves like a normal keypress in any way (if I press shift while 
numlock is disabled, I get zeroes, too. If I hold down any other key, it will 
disrupt the key repeating). The frequency of the key presses varies between one 
per minute and three per second.

I can't work when this happens, so I removed the card for now.
