I see. That's unfortunate. :-(
However, byte counters and packet counters in IPFW and IPF
(and probably PF, but I haven't verified) are already 64bit.
So there _are_ at least a few places where the problem does
not exist.
# ipfw show
65535 26326861627 25395554002225 allow ip from any to any
# uname -m
i386
