  Modified files:
    sys/dev/acpica       acpi_battery.c 
  Log:
  When the EC times out (common with Compaqs), it may report a design
  voltage of 0.  This can result in a divide by zero trap.  Add a guard
  for this case.  The value of lfcap is checked in acpi_battery_bif_valid()
  just before this, so it is safe.
