Yes, that's worked:

% cat /etc/ifconfig.carp0
create
vhid 1 pass password 192.168.2.5 255.255.255.0
% grep carp0 /etc/rc.conf
net_interfaces="ex0 carp0"
%

and on the second of the two machines in the group:

% cat /etc/ifconfig.carp0
create
vhid 1 advskew 100 pass password 192.168.2.5 255.255.255.0
% grep carp0 /etc/rc.conf
net_interfaces="ex0 carp0"
%

Could you expand on that a bit please?  Would the kernel (?) try to 
configure carp before the physical interface?  Do you mean you have 
separate 802.1Q VLANs defined on your NetBSD machine's NIC and one 
(or more) of the NIC's IPs are in a carp(4) group?  If so, could you 
post the contents of the /etc/ifconfig.* files you're using for 
reference?
