(Get the code!)
I just fixed a "stick and auto-repeating" keys problem on my Dell Core2 Duo laptop by adding some boot parameters that disable some kernel features:
highres=off nohz=off noapm
I had originally added these same parameters on two other laptops (Acer Aspire and HP Pavillion, both built around AMD64 CPUs with ATI shared-memory video) to cure their random hard freezes.
It seems likely that either the high-res timer or the tickless feature in the latest kernels is very bad medicine, on certain hardware at least.
