Imagine standing in court explaining to a non-technical judge and jury how this "bridge" transforms the copyrighted work into two fully separated works rather than a single derivative work. Do think it would work?

Personally I think one has a better time arguing that kernel modules simply interface with the kernel rather than creating a derivative work, thus making any module independent from the license of the kernel. The case law around "interfacing" is conflicting, but at least a few cases has gone in favor of the accused.
