FWIW I've been seeing behavior that is almost certainly caused by this
bug for a while, I lose 'control' or 'shift' key-down events and this
is entirely independent of keyboard attached (i've tried several) and
seems to only happen on an SMP box.
It's most accutely annoying if it triggers while playing quake3 :-)
