  Log:
  When enabling A20, put upper limit on amount of time we wait for the
  keyboard controller to get ready (65K x ISA access time, visually
  around 1 second).  If we have wait more than that amount it's likely
  that the hardware is a legacy-free one and simply doesn't have keyboard
  controller and doesn't require enabling A20 at all.
