Just for the sake of completeness: Monitor switching can also be quite
desirable for people working on the text console WITHOUT using the
framebuffer. Since we are talking about laptops, the most obvious
reason not to use the framebuffer is the trouble it makes after a
suspend2ram / resume cycle. This applies to vesafb and even more so to
intelfb, at least it did the last time I checked (two or three major
kernel releases back). It would be very sad if ibm-acpi dropped that
feature as long as there is no alternative for console users too.
