Xorg device disabled with 'Option "Ignore" "true"' still enabled by udev+Xorg. How to fix ?

[ar16]

Hi,

I'm running Opensuse 12.3/64,

    uname -r
        3.7.10-1.16-desktop

with

    X.Org X Server 1.13.2

I've attached a USB IR receiver (Streamzap).

I'm trying to keep Xorg from auto-adding the device as a KEYBOARD or
MOUSE, using udev-discovered device info.

The default Xorg evdev catchall includes

    cat /etc/X11/xorg.conf.d/10-evdev.conf
        ...
        Section "InputClass"
                Identifier "evdev pointer catchall"
                MatchIsPointer "on"
                MatchDevicePath "/dev/input/event*"
                Driver "evdev"
        EndSection

        Section "InputClass"
                Identifier "evdev keyboard catchall"
                MatchIsKeyboard "on"
                MatchDevicePath "/dev/input/event*"
                Driver "evdev"
        EndSection
        ...

Iiuc, the override for just the Streamzap device should be

    cat /etc/X11/xorg.conf.d/05-streamzap.conf
        Section "InputClass"
            Identifier "Ignore Streamzap KEYBOARD"
            MatchIsKeyboard "on"
            MatchDevicePath "/dev/input/event*|/dev/input/mouse*"
            Driver "evdev"
            MatchProduct "treamzap"
            Option "Ignore" "true"
        EndSection
        Section "InputClass"
            Identifier "Ignore Streamzap MOUSE"
            MatchIsPointer "on"
            MatchDevicePath "/dev/input/event*|/dev/input/mouse*"
            Driver "evdev"
            MatchProduct "treamzap"
            Option "Ignore" "true"
        EndSection

but, after reboot,

Which looks like the Streamzap's ignored -- AFTER being assigned -- a
bit confusing as to what's going on.

But, a clear indication that it's not completely ignored is -- if, at
this point, I press the POWER button on the Streamzap, it immediately
powers off my desktop.  Not an action that I'd intended!

How do I completely disable the adding of the Streamzap and its use by
Xorg?
