This is not so simple: when synaptics x driver starts it grabs the event
device using EVIOCGRAB. In this way data from input device don't leak
to /dev/input/mice and, as a side effect, no one else can read events
from event device.
If you are using synaptics X driver you can see this by simply "cat"
your mouse evdev with X turned on and then off: you'll see garbage in
the latter case, but not in the former.
