Depending on who you share a network segement with, you could annoy a whole lot of people with the traffic that this would generate. Also, it probably won't have the desired effect. SYN flood attacks are not designed to crash a system, they are used by vandals to deny service to a particular host or network. The remote power control devices that people have been recommending are much better solutions to this problem. Does your colo provider offer a port on a terminal server that you could use to connect to a serial console on your FreeBSD box? If so, there are serial console cards out there that might be ideal for your situation, although at a cost.
