Comment # 4 on bug 912589 from Egbert Eich

I think I mistyped something in my comment. 
Pint 2. should read:

2. add:
   The section: 
   Section "InputClass"
        Identifier "Wacom Bamboo keypad class"
        MatchUSBID "0x056a:0x0319"
        MatchIsTablet "on"
        MatchDevicePath "/dev/input/event*"
        Driver "evdev"
   EndSection

MatchTablet "on" instead of "off".
