I generally like this idea... But two caveats... First, we'd need to update the docs so that folks doing serial installs can unset it.... Though serial installs are a weird beast.... Second, if it's really needed, we should have the installer generate it. alas, only vt can tell us that, but it should be easy to add a sysctl to it that says that it has done video by ignoring the absence of the vga node...
