Checkout the latest svn of
http://sourceforge.net/projects/wacom-config/

support for settings I4 leds isn't quite complete but I think might be
good enough to help with your testing;

prior to starting wacom-config

find the /sys led dir for the attached I4

e.g.

$ find /sys -iname wacom_led
/sys/devices/pci0000:00/0000:00:1a.1/usb5/5-2/5-2:1.0/wacom_led

then grant 'other' write access

e.g.

sudo chmod o+w /sys/devices/pci0000:00/0000:00:1a.1/usb5/5-2/5-2:1.0/wacom_led/button?_rawimg

then my code should be able to set images for the leds.    (I've not
written code for setting the led indicator yet)

This is the first time I've suggested somebody try this code on a
machine other than my test ones but I can't see any reason why it
shouldn't work,   I've tested with vanilla kernel 3.2 and with the
earlier stand alone patches applier to previous kernels.

Thanks

p.s.   If you have any crashes or other problems send me the output
from running   wacom-config --debug    so I have a full log of what
it's doing/seeing
