I have managed to get Lcdproc to work nowdays for imon. The same driver is
used for two different displays technologies (was it lcd and vfd or
something similar), and at some point you had to manually tell which
technology you actually have. I would imagine that based on usbid it would
be rather easy to make this detection automatic.
