If i find a problem with a given .config, i do _not_ go around and change the .config to make a bisection point work. (and the automated bisection scripts definitely wont do it either.) so what is a 'weird config' to you is a real testing barrier for others. And crap like that quickly mounts up. Having a buildable and bootable kernel at every bisection point is a _must_.
