X has supported multiple keyboards for a few years now, in fact the average
installation these days provides 3 or 4 keyboards by default (Video Bus,
Power Button, etc. they all look like keyboards). I have two
physical keyboards connected on a daily basis, so I doubt that's the reason.

At this point, I'm running out of ideas though. if you see the events
leaving the kernel evdev should just work, especially given that if this was
a common bug _a lot_ of people would be affected.
I don't have any other ideas than attaching gdb to the server and seeing
where the events disappear. EvdevReadInput() is the first function to be
called, from then on it's tracing it through the driver and server to see
where they disappear.
