I perused the FreeBSD sources, just as a santity check (their mc146818
driver is based on the NetBSD one) and I see they had the correct handling
of that bit from the initial import.  In recent sources they've refactored
everything and now don't use it (they just disable RTC updates when
setting the clock).  I'll try some sample code to fix this tonight.
