I don¹t know if it works on BSD, but if so, use Heartbeat instead.  It can
be configured to run whatever you want when one machine takes over.. So you
could have it kill(because you might have auto fail back enabled) then start
haproxy after it takes the IP.  Maybe CARP can do the same thing?

Subject: HAProxy and FreeBSD CARP failover

Hi list. 
I'd like to set up a redundant HAProxy server using CARP failover in FreeBSD
so the spare server will automatically snatch up the "listen" IP and balance
out our server farm. I can get HAProxy configured, but it won't actually
start unless the IP is already bound to the box. Suggestions?

(latest haproxy-devel from FreeBSD ports)
