Works fine on the hardware that started the whole thing. This one requires CONFIG_CPU_FREQ turned off (otherwise the keyboard freezes). Stephen Hemminger's required CONFIG_CPU_FREQ to be set (otherwise the keyboard froze in this case as well, not being able to register interrupts), which made less sense.
good work.
