Thanks!! You are awesome, guys, I wouldn't been able to find this if it was "Googling". I have to take a look now, but it looks cool. If I can just use this X11 hack now, then I have plenty of time to develop a driver (for a near future, maybe, when more functionality should be needed).
All comments will be welcome!!
