This change was actually motived by a request from the Sage project :). As such, I'm sure it will be supported in Sage as soon as Sage upgrades to the newer version of maxima. As for you for now, you'd need to change the eigenvectors() command in the matrix code. If you wanted to do so and submit a patch, it would be greatly appreciated!
