(I'm not sure it's *not* the solution, either). The question I've been looking at is: do sub-second boot times make all this a moot point? After all, if you can bring up your graphics driver in a fraction of a second and use *it* to display a splash screen, it seems like it would meet your need to give almost immediate feedback to users that the system is alive. -- David VomLehn
