Hmm.
Judging from the result, layer 3 is properly working.
So I cannot locate the problem yet...
     - NDP cache is properly created for dc0's local address
     - loopback address exists
     - IPv6 is not disabled on dc0 (assuming usr.sbin/ndp is also
       updated to the latest one, which displays "disabled" if the
       IPv6 operation is administratively disabled)

To narrow the problem further, could you please try with the RELENG_6
kernel at Nov 5 00:00 2005 UTC?  During Nov.1-11, there are two kinds
of kernel MFCs regarding IPv6 (scope clean-up@Nov 4 20:26, disabling
IPv6 per interface@Nov 5 10:30).  And I'd like to know which one
brings about your problem.

Thanks,
