There is an astonishingly simple solution which works with XFree86
4.2.0:
Create a link to the device in /dev:

    cd /dev
    ln -s input/event0 wacom

Now use /dev/wacom in your XF86Config.

When the hotplugging gets in your way, just change the link. X11 will
somehow notice that the device now works again and it will reactivate
it (I have this problem with my USB mouse: Every time, I press the
hotsync button of my PDA, the USB devices are changed. Then, I have
to reset the link and I can work again).
