That's not my experience especially once you get into phone type
hardware - there's not much complexity difference when gluing things
into the system and the fact that it's connected by the board increases
the amount of flexibility that has to be coped with.  I don't see a
substantial difference between the two cases.  To be honest I'm a bit
concerned about what we're going to see given where ACPI's at as a spec.
