I used to have this beast. I had simular problems with it, but I had
managed to overcome them by switching the keyboard to the legacy boot
protocol. I am attaching two old patches, one for the stock USB stack
and one for the HPS stack (the old one, more than a year ago). So, they
can be worthless now, but you can give it a shot.
I had quickly ported my old patch to the current usb20 ukbd2.c, this
patch is attached too, but I have no such keyboard at hand just now, so
I can't test the patches in question. If you will succeed with them --
please, report back.
Thanks!

Untested stuff, produced as the reply to Jeremy Chadwick, see
http://lists.freebsd.org/pipermail/freebsd-current/2008-November/000219.h=
tml
This patch just sets legacy boot device protocol for the USB keyboard,
so it acts as the plain old keyboard, mostly without any fancy stuff like
additional controls and so on.
