Floodgate Computer and restarting the server

So, I have a floodgate, which I use for my automatic farm, and when the server restarts, it isn't quick enough to start up and water gets through for a couple of seconds before it kicks in and moves the pistons. Is there anyway around this?

You could try to use some fancy logic gates using either redstone or the RedPower mod, since redstone always loads before computers.

It's essentially a not gate, so.. I guess, I could just switch redstone output to be false, when the doors are closed and true when they aren't. Thanks
