Default Deadzones for Event based Joysticks

Hi all,
I have a problem when using a gaming wheel with SDL1.3/2.0, which appears
to stem from the Linux event system. By default the deadzone is very large
(approximately 60' on a G27), which make 'driving' very difficult.

I found two solutions:

 1). use 'export SDL_JOYSTICK_DEVICE=/dev/input/js0', but then SDL doesn't
present a haptic interface for that joystick

2). G25Manage, which tells the event interface that there is no deadzone.
./G25manage --deadzone=0 --evdev=/dev/input/event3

Is there a way to configure the default deadzone to '0' so I don't have to
do the above?

Thanks,
Simon.
