I would like to report that with Andre's FreeBSD kernel patch, this now
works fine! Instead of attaching to the HID driver, it now shows up as a
generic device, and with the most recent LCDproc code it works fine and I
can finally start LCDd without an error.
Thanks to everyone involved and I hope this makes it into FreeBSD soon.
