Unfortunately, I can't find anything in the BIOS setup to turn it off. I
can enable or disable the TrackPoint and the TouchPad, but that seems to
be all. 'show hint.atkbd.0.disabled' fails, so I suspect it does not
exist.

I feel like I'm in a bit of a catch-22. Any ideas beyond applying the
patch on another system and building a new release and burning it to CD?
