Not the kernel, the /etc/rc.d/network script.

Yes (so it's not the NIC's IPs but the IPs on the different vlan
interfaces)

Quite easy, something like:
/etc/ifconfig.wm0
up

/etc/ifconfig.vlan0
create
vlan 574 vlanif wm0
inet 10.0.0.1 netmask 255.255.255.0 

/etc/ifconfig.carp0
create
vhid 1 advskew 100 pass password 132.227.1.1 255.255.255.0

(132.227.1.1 being the public IP shared by the 2 boxes, and 10.0.0.1
the IP used for internal communication with the second member of the
CARP).
