Yes, preference is given to xorg.conf, but due to the nature of kbd/evdev interactions, evdev just white-ants kbd. There's a bit of work we can do here (if there's already a kbd device defined in the config file, don't auto-add keyboards), so I'll check it out.

Wouldn't the solution be to add an InputDevice section with evdev as driver and Device as /dev/input/by-id/whatever. This way the x server will apply the configured option to the respective device, and the hotplug-code (which is invoked later) is prevented from taking over the device.
WONTFIX xserver 1.4 probably won't get much upstream love in the future, using evdev as the driver is the way to go. Users just need to learn that the HAL fdi file is the configuration for input devices now. If that's not suitable, use /dev/input/by-id and the evdev driver for devices in xorg.conf.
