I went to colo, and checked what happened, as soon as a type:
ifconfig carp0 10.10.10.110 netmask 255.255.248.0 vhid 7 advskew 100
I get:
ifconfig carp0 10.10.10.110 netmask 255.255.248.0 vhid 7 advskew 100

Version is:
OpenBSD 4.2-current as of Wed Sep 19, 2007
I tried it on two (identical IBM netvista desktops) (actually it's 4
netvistas, but 2 works perfectly well, but as soon as you try to add 3d
one...)
