My main concern with doing this on the kernel side is that it will eventually fall foul of the attempts to reduce everything to a single kernel image, since the code will necessarily be quite kirkwood specific and run very early on. Martin's testing of di on ARM[0] suggests this issue isn't all that widespread, which lead me to conclude that the risk of making a change like this (either in the kernel or the installer/flash-kernel) for Wheezy was not worth the chance of breaking some other kirkwood device.
