Good data, thanks.  Does not match #9453.  Fascinating.

Could you try the latest firmware and see if that fixes it?

For instructions on installing firmware, see ... in short put it on a USB device,
attach battery and AC, and at the OpenFirmware prompt type "flash

If it doesn't fix it, could you use the diagnostic ("test /keyboard") to
figure out for us:

1.  exactly which keys ... (there are two hand keys; are both
affected?), and on which XOs,

2.  whether the intermittency is dependent on the fingers being used,

3.  whether the intermittency is dependent on flexing of the case or
keyboard area, (there's a cable involved, and it may be a cause),

4.  whether the problem goes away for a short time after a full power
removal (battery and AC), (we had something like this on XO-1 B1, long
since fixed, unlikely),

5.  whether any of the keys get stuck in their active state.

If you've logged this one in trac by now, tell me the number.
