Why are we even driving a vt switch direct from the suspend/resume
logic ? The problem starts there. If it was being handled off the device
suspend/resume method then there wouldn't be a mess to start with ?

Start at the beginning

- Why do we switch to arbitarily chosen 'last vt'
- Why isn't vt related suspend/resume handled by the device
