Measured battery voltage: 2.91 at the chip (pins 4 - 7) and 3.2 at the 
battery.
Removed the battery for roughly an hour.  Exactly the same behavior 
(can't read on boot up, can't write when setting date) after 
reinstalling the battery.
I also doubled all of the delays in .../src/sys/dev/i2c/i2c_bitbang.c.  
Same behavior.
The Debian clock driver appears to work - or at least I didn't see any 
errors on the console or in /var/log/messages.  On the first boot-up 
into Debian, the clock was wrong, but OK the second time the Slug was 
booted.

Thanks for the suggestion, but RTC lockup doesn't appear to be the 
problem.  If I have time tomorrow, I'll compare the Debian startup to 
the NetBSD startup code.
