Fiddling around with ipfw, I noticed that 'ip6fw -ta l', under byte

IPv4 byte statistics, on the other hand, include the IPv4 header bytes.
Is this a known problem? Is it a more general BSD kernel problem?
Probably, you should use ipfw(8) instead of ip6fw(8). ip6fw was removed and
it's functional moved into ipfw(8).
FWIW -- a rule generated by ipfw(8) counts the length correctly.
