    Hmm .. I misssed whatever started this, but I've noticed that under
    recent kernels, my key repeat is pathetically slow, basically the default
    for the keyboard. I would think it should be set by some config utility
    like Gnome or something, but it doesn't seem to. I have to hit Fn-F6
    (which is my keyboards way of setting a faster key repeat). Kinda
    annoying - whatever changed .. it was better before :P
