  Modified files:
    sys/i386/isa         clock.c 
  Log:
  Use a simpler implementation for the i8254 timecounter when using the lapic
  timer since irq0 isn't being driven at hz in that case and we don't need to
  try to handle edge cases with rollover, etc. that require irq0 to be firing
  for the timecounter to actually work.
