Yup, same here - aactually running a very recent STABLE now,
but for most of this year it's been on one from January. The
one running on the firewalls is from May 7th, and that works
beautifully.

Ok, let us know how you get on - the config here is very simple, reproduced
below for your viewing pleasure ;) This is from the 'active' firewall:

	ifconfig_em0="inet 10.32.10.1/16"
	ipv6_ifconfig_em0="2a02:1658:1:2:a32f::1/64"
	ifconfig_em1="inet 178.250.73.196/27"
	ipv6_ifconfig_em1="2a02:1658:1:1::1:2/64"

	ifconfig_carp0="vhid 10 pass xxxxyyyy 10.32.10.6/16"
	ifconfig_carp1="vhid 20 pass xxxxyyyy 178.250.73.198/27"
	ipv6_ifconfig_carp2="vhid 30 pass xxxxyyyy 2a02:1658:1:2:a32f::6/64"
	ipv6_ifconfig_carp3="vhid 40 pass xxxxyyyy 2a02:1658:1:1::1:1/64"
