Yes, there is a "disasterlessmod". I believe it was written by Arklon. I think the source is in SVN. Might try searching the forums for a downloadable zip file. I think there was one posted, but I'm not seeing it off the top of my head. If you can't find it, perhaps someone can compile the source from SVN and upload a zip file.
Failing that, there are also tutorials on how to use OllyDbg, and a typical easy example of using it is to disable disasters. If you're looking to learn something, that might be a fun way to do it.
