When pressing a key (in xterm, emacs, galeon,...) the keyboard repeat rate is
first high, but after about 20-30 characters (less than 1 second) it slows down.
According to http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=134110 , this
is connected to the `kbd' driver and was not a problem with the old 'keyboard'
driver, but in my version of xorg, keyboard_drv.o is a copy of kbd_drv.o, so I
cannot verify this.

Here's my settings from xset:

  Keyboard Control:
    auto repeat:  on    key click percent:  0    LED mask:  00000000
    auto repeat delay:  200    repeat rate:  66
    auto repeating keys:  00ffffffdffffbbf
                          fadfffdfffdfe5ef
                          ffffffffffffffff
                          ffffffffffffffff

and from /etc/X11/xorg.conf:

  Section "InputDevice"
        Identifier  "Keyboard0"
        Driver      "kbd"
  EndSection
