Comment(by Quozl):

 Turning off square wave output mode of the chip reduced probability of
 failure.

 (Tested by disabling the square wave output mode in the chip, using " {{{
 /dev/rtc 0 7 rtc! }}} " ... this made it possible for a short power cycle
 " {{{ reboot }}} " in OpenFirmware to preserve the time, but a long power
 cycle in Linux or with the power button still lost the time.  The time
 shown by the RTC registers corresponded to the wall clock time since power
 off, not the wall clock time since power on.  This shows the stored value
 is lost when the power falls.)
