Ooh. I've never tested this on 64 bit before. I'll investigate after
work today to see if that's an issue.

Alrighty, that's the device I've got.

You need TCL (and TK) to build wacomcpl. You need ncurses for wacdump.
IIRC, sudo apt-get install tcl8.4 tk8.4 libncurses5-dev will do the
job.
See above.

Calibration doesn't exist unless you edit xorg.conf. It pretends it's
a regular (i.e. relative) mouse device, and being a touchscreen device
this only leads to badness. Once you edit xorg.conf, it will be nice
and linear.

Here's my config segments:

Section "InputDevice"
    Identifier     "TabletPCStylus"
    Driver         "wacom"
    Option         "ForceDevice" "ISDV4"
    Option         "Type" "stylus"
    Option         "SendCoreEvents" "true"
    Option         "Device"
"/dev/input/by-path/pci-0000:00:0b.1-usb-0:2.3:1.0-wacom"
    Option         "TopX" "225"
    Option         "TopY" "122"
    Option         "BottomX" "26365"
    Option         "BottomY" "16488"
EndSection

Section "InputDevice"
    Identifier     "TabletPCStylus2"
    Driver         "wacom"
    Option         "ForceDevice" "ISDV4"
    Option         "Type" "stylus"
    Option         "SendCoreEvents" "true"
    Option         "Device"
"/dev/input/by-path/pci-0000:00:0b.1-usb-0:2.3:1.1-wacom"
EndSection

Section "InputDevice"
    Identifier     "TabletPCStylus3"
    Driver         "wacom"
    Option         "ForceDevice" "ISDV4"
    Option         "Type" "eraser"
    Option         "SendCoreEvents" "true"
    Option         "Device"
"/dev/input/by-path/pci-0000:00:0b.1-usb-0:2.3:1.0-wacom"
EndSection

Note: Do NOT change any of the identifiers. Changing them to anything
else unless you know EXACTLY why they're the way they are will break
wacomcpl (i.e. don't change them). The "Device" sections are based on
my tx2000z, so they may have changed for the tx2500 (look in the
/dev/input/by-path folder). 1.0-wacom is the pen/eraser, 1.1-wacom is
the touch (No, the "Type" "Stylus" is not a typo. Just trust me.)

This might have something to do with being on 64 bit. (The number is
255 by the way) After work today I'll investigate (as mentioned
above).

I'll send you a debug patch after work today, and then you can send me
your dmesg and I can go from there.

Thanks for the report
