Acer TravelMate C112 Ti Wacom touchscreen

Okay, thanks to Danny Kukawa for detection instructions,
you will need to do the following, and I am assuming for
now until I can set it up myself that you are competent at
turning this into proper boot-time-setup "stuff" :)

	apt-get install wacom-utils
	modprobe wacom
	setserial /dev/ttyS0 port 0x06f8 irq 6 autoconfigure
	wacdump -f c100 -c serial /dev/ttyS0

then if that works, exit and then add the following likes to xf86config
or to xorg.conf (yes you can get Xorg for Debian, works a treat,
see e.g. http://debian-desktop.org/pub/linux/debian/)

Oh - btw - I don't use xfree86 any more, but when I did (on my C100),
i had to manually recompile the wacom xfree86 driver with a patch
in it to support 115200 baud.  It's a long stupid story but the gist
of it is that the setserial command set up the C100's touchscreen
device at 115200 baud, autoconfigure didn't work, and the options
on the wacom driver will only allow 9600, 19200 and 38400 baud as
driver options.

Whether that (having to recompile the wacom driver) affects the success
or otherwise of the config below for a C112's Wacom device is yet to
be determined (give me a day or so!!)

Good Luck - and yes, I suggest you dump xfree86 and use Xorg
on your debian system ASAP.  Works a treat on the C112 and C110s.
