    I've seen this junk for many years. It's not limited to just 2.6.

    In my current environment, it's the KVM screwing with the mouse data...
    somehow it starts passing through 3 byte commands when the mouse is in
    4 byte mode. I fixed it by a little trickery to force the mouse to
    reset (not a simple task from the ISR :-) BTW, 250ms is WAY to long to
    wait to detect a lose of sync; mice don't pause at all between bytes.)

    And exactly what is that supposed to be fixing?
