Just to compare... Also, according to sample config, x11-drivers/xf86-input-wacom uses /dev/input/event for input, I don't know how those get created. (There are four of them.) With webcam, I am getting # webcamd -d ugen0.6 webcamd 4480 - - Attached to ugen0.6[0] webcamd 4480 - - Creating /dev/input/event6 and now I see some action on touch, but it looks like some calibration is necessary - I have two monitor setup and position set is correct in one axis but offset in the other. As there is USB used for connection, iichid probably is no help for me :) So I am a bit better now, with single monitor setup, it would probably work as is (a bit), so some more investigation is necessary.
